Key features

• Thrust washer for use with Koyo Torrington NTA-series thrust needle roller and cage assemblies in applications where adjacent components cannot serve as raceways

• Flush-ground raceways for higher speeds and greater running accuracy than unground raceways

This Koyo TR-series thrust roller bearing washer is designed for use with Koyo NTA-series thrust needle roller and cage assemblies in applications where adjacent components cannot serve as raceways. This thrust washer serves as a raceway surface for the thrust assembly’s rolling elements and can be used as a shaft washer (bore-piloting washer) fixed on the shaft or a housing washer (outer diameter-piloting washer) fixed in the housing. Both sides of the washer can be used as raceways and are flush ground for higher speeds and greater running accuracy than unground raceways. The washer is made of low alloy, through-hardened chromium steel for durability, heat tolerance, and resistance to deformity under heavy loads. This thrust washer is for use in various applications including machine tool drive shafts, automotive steering gears and clutches, rotary tables, outboard motor propellers, and household appliances. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rol
