C . 70 series Angular Contact Ball Bearing Details
Product Features Precision Angular Contact Ball BearingsDue to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing.

D . 70 series Angular Contact Ball Bearing Installation & Cautions
"Installation:
To obtain the best possible performance of the bearings, installation must be performed very carefully in ultra clean conditions.
Errors during fitting of ball bearings can jeopardize the best design and create high repair and maintenance costs. We would like to give some advise for proper mounting of bearings:
The workshop should be dust free with low humidity, no compressed air or machining is allowed.
Only unpack bearings immediately before installation. If grease is required it should be applied at this time, with a syringe. Do not use fingers or a spatula.
The use of a syringe is recommended to inject the grease right between the balls into the ball/raceway area. Nearly all standard greases are compatible to our rust preventive, so in most cases it is not necessary to wash the bearings prior to greasing. The only exceptions are special greases, based on silicone or fluorocarbon oils or PTFE-thickeners. They require a clean oil free surface to obtain good adhesion of the grease.
Never clean the bearings in ultra sonic devices! Allow the rust preventive to dissolve in a gasoline bath by slowly moving the bearings."
