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 MKSP/MKSP-A SAE-AS7949 Precision Series airframe control self aligning bearings are single row, heavy duty (MKSP) or medium duty (MKSP-A) ball bearings with PTFE seals and CRES sealcaps. These bearings are self aligning for 10 Deg. in either direction  except those with part numbers MKSP4A, MKSP5A and MKSP6A which are self aligning for 8 Deg. in either direction. The RBC® BEARINGS MKSP/MKSP-A bearings conform with MS27645-R specifications. External surfaces (except bore, caps, and seals) are cadmium plated. They come prelubricated for life and are also offered with CRES 440C material and/or zinc nickel plating per OEM specifications. For additional information please refer to the supplied documentation.

INA, LuK, and FAG brands of bearings are part of Schaeffler Group portfolio, a worldwide leading manufacturer of bearings and other precision products for automotive, motion control and applications for aviation and aerospace.

INA Bearing Company is dedicated on the production of extraordinary quality roller bearings, plain bearings and linear components.

INA Thrust Bearings include an extensive range of Ball Thrust, Roller Thrust, Double Direction Thrust and Self Aligning Thrust Bearings available in a wide collection of ISO, DIN and popular inch and metric series. Races are made from through hardening and case hardening steels. Cage materials include phenolic, steel, plastic, aluminum and bronze. Selective sizes of INA Ball Thrust Bearings are available from stainless steel.

INA Ball Thrust Bearings are offered as banded, 3 piece grooved race, 3 piece flat race and self aligning series.

INA Roller Thrust Bearings are available as complete bearings or cage and roller assemblies and washer components.

INA Double Direction Thrust Bearings are available as complete bearings in ball series or component groups of cage and roller assemblies and ZS washers.

INA Self Aligning Thrust Bearings are available as complete bearings with the self aligning seats sold separately.

TIMKEN® tapered roller bearings are characterized by reliability, versatility and choice. They stand up to extreme situations, including high-corrosive, high-temperature, vacuum or low-lubrication environments. Uniquely designed to manage both types of loads on rotating shafts and in housings and offer a choice of nearly 26,000 product combinations, from single, double to four-row configurations and thrust bearings. Each bearing contains four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered angles allow bearings to efficiently control a combination of radial and thrust loads. The steeper the outer ring angle, the greater ability the bearing has to handle thrust loads. To provide a true rolling motion of the rollers on the raceways, the extensions of the raceways and the tapered surfaces of the rollers come together at a common point, the apex, on the axis of rotation.

TIMKEN® Single Row (TS) bearings are basic and most widely used. Usually fitted as one of an opposing pair. They can be “set” to the required clearance (endplay) or preload condition to optimize performance. TSF type bearings, a TS variation, have a flanged outer ring to facilitate axial location and accurately aligned seats in a through-bored housing.

TIMKEN® Double Row Outer Ring bearings (TDO)  have a one-piece (double) outer ring and two single inner rings. Usually supplied complete with an inner-ring spacer as a pre-set assembly. They offer a wide effective bearing spread and frequently chosen for applications where overturning moments are a significant load component. Other bearing types include TDI (double-row double inner race) and TDIT (same as TDI with tapered bore). Both comprise a double inner ring and two single outer rings. Usually supplied complete with an outerring spacer as a pre-set assembly. TDI and TDIT bearings can be used at fixed (locating) positions on rotating shaft applications. Offered types include: TNA (double-row non-adjustable), TNASW (same as TNA with lubricant slots) or TNASWE  (same as TNSW with extended back face rib). They are similar to the TDO with a one-piece (double) outer ring and two single inner rings.  Supplied with a built-in clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications where optimum simplicity of assembly is required.

For aerospace applications, different FAA PMA approved tapered single roller bearings are offered including TIMKEN® 13600, 13800 and LM813000 Series with a cone assembly and a cup. Offered in "inch" and "metric" versions LM813000 Series feature  minimization of friction between the rotating parts, handling of thrust loads, even load distibution across the roller, heavy load carrying capacity & stamped steel cage.

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.
