About Jesel Tool Steel Cam Cores

Jesel’s CNC turned tool steel cam cores are custom-machined to meet your exact specifications, offering unparalleled precision and reliability for high-performance engines. With journal sizes ranging from 50mm to 88mm and the ability to machine custom lobe layouts, we can craft cam cores from your detailed prints or reverse engineer them from an existing design. All engineering data is treated as proprietary and securely maintained for your exclusive use.

Crafted from high toughness, through-hardened steel, Jesel cam cores are designed to withstand the extreme contact stress and shock loading associated with today’s high spring pressures, ramp speeds, and ratio combinations. This robust material ensures superior surface strength and durability, making Jesel cam cores the preferred choice for demanding racing applications.

Coated Babbit & Needle Bearings

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.
