As double acting packings, the RGU-packings have a unique seal lip shape and provide identical sealing performance to U-packings on compacter sized pistons. Frequently be in service as a combination system with the PWL-bearings which offer multi-functions-bearing & back-up ring.

Cylinders for machine tools and industrial vehicles
S-FLON (PTFE) seals and back-up rings are combined to achieve low friction characteristic and of elimination stick slip even at low pressure/speed conditions.Moderate sealing performance comparing with U-packings due to the PTFE plastic seals which have higher rigidity and lower elasticity than rubber materials.
