Jesel’s Babbitt camshaft bearings incorporate a lead based alloy babbit material that is applied to a precision centerless ground seamless steel back. This Babbitt material, in conjunction with a dry-film polymer lubricant, protects the bearing surface from damage due to instances such as cold starts, low oil flow and catastrophic loss of oil pressure.
In an effort to reduce oil windage and oil aeration from the camshaft, Jesel offers encapsulated needle-bearing camshaft bearings for a 50 to 70mm cam core. The low friction rollers are designed to operate with a minimal supply of oil. If you will be running a belt drive with this bearing, provisions need to be made to suppliment the oil supply to the thrust washers of the belt drive.
