Description Direct fit OE replacement steel bearings ID 20mm x OD 47mm x Width 14mm Light contact seals Chevron SRI-2 grease C3 internal clearance High Speed 1pc Nylon cage Radial ball bearings 2 year warranty Worldwide Bearings meet the demanding requirements for high speed, performance and durability. Designed as a high quality, direct fit OE replacement, these bearings come standard with Chevron SRI Grease, a high temperature ball and roller bearing grease. Worldwide steel bearings utilize Chevron SRI Grease, a high temperature ball and roller bearing grease. It is formulated with ISOSYN® base stocks, a synthetic polyurea ashless organic thickener, and high performance rust and oxidation inhibitors (the latter to provide superior rust protection in severe applications). Its texture is smooth and buttery and its color is dark green. Chevron SRI Grease passes ASTM D 1743 73 rust test with 5% synthetic sea water. It gives longer bearing life under high speed and high temperature operation than most other widely used antifriction bearing greases. ASTM D 3336 tests show that the life of a 204 K bearing lubricated with Chevron SRI Grease and operating at 150°C (302°F) and 10,000 rpm is about 3000 hours. This is nearly 10 times the life possible when using conventional lithium greases. All Worldwide Bearings come with a 2 year warranty.
