The HEIM® BEARINGS company has been acquired by RBC® BEARINGS, a leader in the world of highly engineered bearing products. 

HEIM® BEARINGS produces the industry's widest range of rod end bearing sizes (aka rod ends) in the following four grades (types): precision, aircraft, military and commercial with each grade including different series suitable for respective application requirements. HEIM® BEARINGS are made from different materials featuring among others high strength two piece designs, high capacity designs, self-lubricating options and thermoplastic races or Teflon® liners. Please consult the supplied table on different grades and series offered.

- Precision rod ends are manufactured to tight tolerances for applications requiring improved linkage accuracy and reduced looseness. 

- Aircraft rod ends use premium materials, and have magnafluxed rod end bodies. Originally intended for aircraft applications, aircraft rod ends are used in many industrial applications where a high degree of reliability is required

- Military rod ends are produced in strict accordance with all applicable military specifications and are typically used in military and commercial aviation applications, or when Mil-Spec approval is required

- Commercial rod ends are produced using standard materials and manufacturing methods, and consist an economical choice for industrial applications

The HEIM® BEARINGS HM M/HF M Series aircraft rod ends, male and female threaded respecively,have rod end bodies made from aircraft quality carbon steel and magnafluxed for a high degree of assurance of rod end integrity. Balls  are made from 52100 alloy steel, heat treated and chrome plated on brass race inserts. These series were originally intended for general aviation applications and is also used in many industrial applications where rod end reliability is critical.

Miscellaneous Aerospace & Milspec bearings by various manufacturers specified by either their Part Number, US National Stock Number / NATO Stock Number (NSN) (*) or both. Listed bearings are supplied in New Condition or other Condition as specified for the respective item. Listed products are NCNR Non-cancellable/non-returnable upon order placement. Any inventories of our co-operating suppliers are always subject to prior sale. 

(*) The National Stock Number or NSN is a 13-digit stock number used by U.S Federal agencies, including the DOD to buy and manage supplies of repeatedly procured, stocked, stored, issued, and used items. It consists of the four-digit Federal Supply Classification (FSC) and the nine-digit National Item Identification Number (NIIN). The NIIN consists of a two-digit National Codification Bureau (NCB) number followed by a seven-digit item number. This number is also used by the North Atlantic Treaty Organization (NATO) and the international community as both NSN and NATO Stock Number are interchangeable terms for the same codification system.

Supply of listed bearings may require compliance with the International Traffic in Arms Regulations (ITAR) which control the export and import of defense-related articles and services on the United States Munitions List (USML). According to the U.S. Government, all manufacturers, exporters, and brokers of defense articles, defense services, or related technical data must be ITAR compliant.

The RBC® BEARINGS offers a full line of airframe control ball bearings to the aerospace industry  in both “Standard” and “Precision” series. The prefix “M” in a bearing number indicates that it is of a precision series. Although designed and manufactured under demanding quality control requirements for airborne systems, these bearings have been successfully used in many industrial applications, where oscillatory movement, high loads, or corrosive environments are prevalent.

RBC® BEARINGS airframe control ball bearings conform to SAE-AS7949 (formerly MIL-B-7949) and many major OEM specifications. These bearings are of lightweight design, corrosion-resistant, grease-lubricated, and typically sealed. Airframe control bearing rings and balls are made of hardened bearing alloy, AISI 52100, with all exposed surfaces, except bearing bore, caps and seals, plated for corrosion protection. For improved corrosion protection, RBC® BEARINGS  supplies bearings made of hardened stainless steel alloy, AISI 440C. This alloy may be passivated or plated with cadmium or zinc nickel for enhanced corrosion protection.

The RBC® BEARINGS Airframe Control Ball Bearings are offered in different series. The KP/KP-A and KSP/KSP-A series, presented separately, are briefly discussed below.

KP (Heavy Duty) and KP-A (Medium Duty) SAE-AS7949 Series radial ball bearings  manufactured with Plyoseals. KP heavy duty single row sealed bearings comply with MS27640 specifications while KP-A medium duty single row ball deep groove sealed bearings with MS27641 specifications. Both KP and KP-A radial ball bearings are prelubricated for life and feature PTFE seals and CRES sealcaps, cadmium plated exposed surfaces except bore, caps, and seals. Both are also offered with CRES 440C material and/or zinc nickel plating per OEM specifications. Load limit ratings: Radial 1230-lbs, thrust 300-lbs.

KSP/KSP-A Series SAE-AS7949 Series single/double row, self-aligning, light and heavy duty ball bearings with bonded PTFE seals and cadmium plated exposed surfaces except bore, caps, and seals. Like those of KP/KP-A Series, both KSP and KSP-A bearings are prelubricated for life and are also offered with CRES 440C material and/or zinc nickel plating per OEM specifications.

Metal cables are are stranded wires used in a wide variety of applications in aviation and many other industries. The term "wire rope" is also used when the cable diameter is larger than 3/8" (9.52 mm), with smaller gauges designated as cables or cords. They are specified in terms of their construction by the number of strands times the number of wires in each strand. For example, “7x19” means the cable with seven (7) strands, and 19 wires in each strand. 7x19 is the most flexible cable, approximately twice as flexible as its 7x7 counterpart.

Aircraft cables are encountered on or around the aircraft including flight control surfaces and tie-downs or other uses. In contrast to the commercial (industrial use) cables, aircraft  cables undergo extensive testing and are lubricated providing substantially better fatigue life. They conform to MIL-DTL-83420 specification. Sourced by leading manufacturers such as CONTINENTAL CABLE or CENTRAL WIRE Group of Companies (CWI) they are offered with or without coating (jacket) in different constructions, materials (such as galvanized carbon steel or stainless steel), diameters in inches and pre-cut or cut-to-order lengths in feet. Many of the offered aircraft cables are also included in U.S. DoD Qualified Products List (QPL) which relates to products, components, or materials, often used in aerospace or military applications, which have been examined, pre-tested & found to conform with all applicable standards or qualification requirements set by a certifying organization or government entity. 

Different flight control cables, general use cable, cable assemblies and related parts from various manufacturers (*) are also offered either as OEM or FAA-PMA approved parts including our own labelled (AVIATIONEU NEW ERA) product lines aircraft and industrial (general use) cables for applications when no compliance to MIL specifications is required. For additional information please consult the Product Description section and the supplied documentation.

(*) OEM aircraft cables & assemblies are offered from TEXTRON AVIATION and are intended for use on Cessna, Beechcraft and Hawker aircraft. FAA-PMA approved aircraft cables and parts are offered from McFARLANE® AVIATION and other manufacturers for use on different aircraft.

Garret GTX GEN II Series Turbochargers are similar to the first GTX series but with enhancing innovations. Their key features include forged fully-machined billet aluminum compressor wheels with next generation aerodynamics that provide a larger horsepower range and maximize boost response.

RBC NICE 5000 Series bearings are similar in construction to those of 400 Series except that they have a flange on the outer ring to locate the bearing when pressed into a tube or housing, thus eliminating the need for an external mounting device. Designed for moderate loads and speeds (not exceeding 1200 rpm) where running accuracy and noise level requirements do not warrant the more expensive precision ground bearings. They feature a full ball complement without a retainer. The rings are case hardened and the soft steel band on the outer ring of the unitized assembly allows the bearing to be pressed into a housing without the necessity of close housing tolerances. The bearings are supplied pre-greased as a standard.
