BMS-50, 5 ton Capacity, 16 mm Stroke, Single Acting Spring Return Cylinder

RC-TRIO is the next generation of the legendary Enerpac RC-Series single acting hydraulic cylinders. These hydraulic jacks include many advanced features to ensure superior durability, versatility, and productivity.

Overview

RC-TRIO is the next generation of the legendary Enerpac RC-Series single acting hydraulic cylinders. These hydraulic jacks include many advanced features to ensure superior durability, versatility, and productivity.

A pre-tensioned spring provides fast plunger retraction and enhanced productivity. The robust bearing system features composite wear bands and a hardened stop ring to resist side-load which minimizes damage and repairs. The plunger wiper, high-grade polyethylene seals and tough external finishes also help towards an extended service life.

With so many hydraulic cylinder models to choose from, we’re confident you’ll find the perfect match for your applications, and if you already own prior RC-Series cylinders, the good news is the new cylinders share the same familiar dimensions and threads for full compatibility.

Features
  • Bearing system with composite wear bands for optimal sideload resistance
  • Strengthened stop ring improves durability and side load resistance
  • Trio Hybrid pre-tensioned spring system provides faster retraction
  • High-grade polyethylene seals for low wear and long service life
  • Plunger wiper reduces contamination, extending cylinder life.
  • Collar and plunger threads and base mounting holes enable easy fixturing (on most models)
  • Standard certified lifting eyes on cylinder models above 55 lbs. (25 kg) weight.
  • Interchangeable with optional CHM6 carrying handle
  • Designed for use in all positions
  • Baked enamel finish for increased corrosion resistance
  • Includes CR400 coupler, dust cap and collar thread protector
  • RC-Series model numbers, external dimensions and threads remain unchanged from prior RC Series cylinders

Product Features

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