BMS SERIES SINGLE ACTING, GENERAL PURPOSE CYLINDER

Capacity: 5-1000T     Max. Pressure: 700 Bar     Spring Return

The BMS-SERIES is a general purpose spring return cylinder designed for use in production, Maintenance and fabrication applications. All BMS-Series cylinders feature a hard chrome cylinder bore and piston rod for maximum corrosion resistance. When combined with the bronze overlay on the piston bearing area and low friction surface treatment on the gland nut, this cylinder is suitable for the demanding applications. Cylinder body mounting threads and base mounting holes are included on most models. Optional tilt saddles are available for all models.

Features of BMS SERIES SINGLE ACTING, GENERAL PURPOSE CYLINDER
  • 1. High strength alloy steel body is precision machined to reduce wear and features a baked enamel finish for durability and corrosion protection
  • 2. Hardened and chromed piston reduces wear and corrosion
  • 3. Heavy-duty, straight pull return springs provide quick retraction times
  • 4. Industrial U-cup style seal prevents costly leaks
  • 5. Hardened alloy steel guide ring elimates over travel and provides support to reduce wear from off center loads
  • 6. Heavy-duty wiper ring keeps dust and debris out of the cylinder body, improving perfomance and service life of the cylinder
  • 7. High strength composite bearing provides support for off center loads without damaging the cylinder walls
  • 8. Standard coupler provided with dust cover
