This is because we have developed iglide® J4 plastic spherical balls for pillow block bearings and fixed flange bearings with steel housings

Our slim replacement balls for pillow block and fixed flange bearings with steel housings offer many technical advantages such as resistance to dirt, low weight, and, of course, absolutely no lubrication or maintenance.
However, the long-established bearing variants work in many applications. The iglide® J4 low-cost spherical balls provide an especially low-cost alternative that is also maintenance-free.
