Precision cylindrical rollers are mainly used as bearing rolling elements to transmit torque and reduce friction. They can also server as precision shafts or as pricision loacting pins. Needle Rollers are used in automotive transmissions, universal joints, front wheeldrive, constant velocity joints water pump bearings, roller clutches, rollerized cam lifters, rocker arms, cam rollers, starter drives and as pins and dowels for various applications.
 

Needle Bearing Accessories Needle Rollers Description: Needle Rollers are mainly used as bearing rolling elements to reduce friction and torque in rotating and pivoting applications. However, these precision rollers have many other uses such as shafts or locating pins. Applications: Vehicle and industrial transmissions, universal joints, and two-cycle engines. Types: Flat ends, rounded ends. Sizes: Diameters from 1.5 mm (0.0591 in. ) to 14 mm (0.551 in. );
 

AISI 440C balls are a martenistic-type stainless steel, which is used extensively in bearing applications that require corrosion-resisting properties.440C balls are resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration, alcohol, blood and foodstuffs.Maximum resistance to corrosion and tarnishing is only achieved when 440C is fully hardened and surfaces are polished to a high luster.HRT provides 440C balls in vacuum melt condition upon request.
