100 percent compatible with SN5

100 percent compatible with SN5

Only a few manufacturers in the world make unitized SN dimension metric units. However, our unitized SN is the only 100% compatible unit with standard SN5 in the world. Because the competitors use one size smaller bearings than standard SN5 bearings. Why? Because they use their adapter mount inserts which are same O.D. as their setscrew lock inserts although SN5 uses taper bore 222XX bearings with the adapters. Please check the chart below. The bearing sizes listed in red are smaller O.D. sized insert than standard SN5 bearings.

Their center heights and mounting pitches of housings are same as SN5, so they use larger housings with smaller insert to mach the dimensions. The smaller O.D. size has reduced load carrying capabilities and may lead to shorter bearing life. The long time SN5 users can’t expect the same bearing lives to those unitized SN5 units. We use the standard adapter sleeves in our patented CROSSLOC™ and this is why we are 100% compatible with SN5.

We are trying to be competitive on price as much as possible even with one size bigger inserts than others to achieve our goal. That is to replace all SN5 in the world with our SN to make them easier.

SN5 Compatible Unitized Units - Smaller Bearing than Standard SN5 is used in the red area.

Our competitors sizes listed in red use a larger housing with a smaller O.D. sized insert than a normal SN5. The smaller O.D. size has reduced load carrying capabilities and may lead to shorter bearing life.
