Ultra-compact roller guide system featuring 90° orthogonal roller arrangement for exceptional moment load resistance. The hardened stainless steel raceway (HRC58-62) ensures wear resistance in contaminated environments. Integrated oil retention grooves maintain lubrication efficiency, while the staggered roller pattern eliminates clearance fluctuations during reciprocation.
