PRODUCT INFORMATION New Low-Friction TRB with Plastic Cage

Development background New Plastic Cage Technology offers Breakthrough in Performance and Functionality If lubrication is excessive 1. It Reduces Agitation Resistance Narrowing bearing lubrication inlet and the interior area reduces surplus lubrication around the rollers. 2. It Improves Lubricating Performance Adding oil pool ensures the lubrication reaches roller ends. 3. Maintains Bearing Strength Using NSK proprietary material that withstands harsh operating conditions A design optimized to minimize stress 2

Product Feature 1: Reduces Agitation Resistance Regulates Lubrication Agitation Resistance Conventional Bearing Steel cage design allows larger volume of lubricant to flow in, resulting in increased agitation resistance. Cage Outer race Cage design based on computational fluid dynamics minimizes surplus lubrication around rollers. Cage Outer race Lube Lubrication Inner race Inner race Cross-Sectional View Cross-Sectional View Lubrication inlet narrowed and interior area reduced. Narrowing Bearing Lubrication Inlet and Interior Area Reduces Surplus Lubrication Around the Rollers 3

Product Feature 2: Improved Lubricating Performance Controls Flow at Lube Outlet Conventional Bearing Danger of seizing up as lube flows out easily. New Bearing Regulating lubrication outflow to the side ensures that the lubrication reaches the roller ends. Lubrication Oil Pool (Retention groove) Adding Oil Pool Ensures that the Lubrication Reaches the Roller Ends 4
