Line bearings, moving smoothly in a low noise.High-performance linear bearing, combining high production efficiency and perfect quality.
FZ Ball Retainer cage Bearing Bushing Brass ball cage bearing retainer
Material: copper, aluminum, plastic, a large number of spot, non - calibration.Standard specifications are in stock
linear bearings are respectively made of copper alloy, hard aluminum alloy and POM resin as the matrix, and holes with proper size and special shape are processed on the surface of the outer circle, in which rolling bearing steel balls are inserted.Using the latest technology of grooved circumferential ball locking, the problem that traditional ball locking and indentation ball locking cannot prevent steel ball from falling off is effectively solved.Work out at the bottom of the bore 90 ° seam allowance to rotate freely within the steel ball in the hole and not fall off.Due to the diameter of the ball more than keep the ring wall thickness, so when use remain higher than that of steel ball ring, cylindrical surface, direct contact with the match of the hole and shaft, the substrate (circle) floating in the middle, and match the difference between the hole and shaft radius less than the diameter of steel ball, steel ball and fits for interference fits, with high precision, flexible shaft and hole relative motion.Is to maintain the cycle of replacement products.
FZ Ball retainer is based on copper or aluminum or POM material, with high quality steel balls, produced in certain angle and density. It's used on cold punching mold and machine tools and so on.
Ball retainer are as copper, aluminium, POM base FZ ball retainer, linear bearing, ball cage retainer
The new work-craft will prevent the ball getting out of as old. as the ball diameter is larger than the retainer s thickness, so it will face to face directy with 90°guide bushing, that will bring high precision match now the ball retainer series items are designed to rotate on the post
As the raditional work-craft has some grudge between bushing with posts, and the coefficient of friction is larger. now we have changed the work-ways to steel-ball directly face guide bushing, so the precision is improved. It composes of both active roll and lower friction coefficient, now they have been widely used in punching machine, die machine, high precision machine which need rotation and vertical motion.
