SFERAX SL 2028 BA

1910.002028.11

Application
The type SL is a SFERAX innovation and a unique product on the market. It was designed for rational and cost-efficient applications, for which the main requirements are:
– reduced mounting space
– high reliability
– good precision
– small weight in motion
– low-cost, without any compromise on the SFERAX-Quality
– simplified mounting
(self-locking)
Features
The SL Series is assembled by shrink-on technique (self-locking), simplifying the mounting, eliminates glue, axial circlips or any other type of axial restraint. Assembly costs are therefore reduced. Also available in SLX version (housing in stainless steel and balls in Stainless Steel 1.4034).
