► Body type: ID Wheel with Shank, ID Wheel without Shank
► Model type: 1A8, 1A1W, 1A1, DWA
A hydraulic tappet is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. Pressurized oil enters through a hole in the lifter’s body and flows into a narrow channel. This oil enters the internal lifter cylinder but flows freely out the other side. When the cam presses down on the lifter piston, it closes the channel.

What is the vitrified CBN internal grinding wheel?
Ceramic CBN internal grinding wheels are made of cubic boron nitride abrasives and sintered with metal powder, resin powder and ceramic as a bonding agent to form various shapes of abrasives for industrial grinding, polishing and lapping. This kind of ceramic internal grinding wheel maintains the original high hardness performance of vitrified grinding wheel, low sintering temperature, high strength and toughness, good abrasive holding performance, and has the characteristics of heat resistance, oil resistance, water resistance, acid and alkali resistance, good self-sharpening, dressable and long dressing interval. Uniform porosity for easy cooling, chip removal, etc. It does not block or burn the workpiece in the grinding process, does not cause chemical changes with the Iron group elements, shows its inertia, reduces the fatigue of the workpiece in the grinding process (ID/OD grinding), increases the service life of the workpiece, thus improving the quality, roughness and efficiency of the processed workpiece as well as the automation of the processed workpiece, and achieving the purpose of reducing the comprehensive cost.
