Parker HBB Cylinder
Manufacturer: Parker

HBB is a base slide for heavy duty linear motion between supports, powered by NFPA or ISO cylinders. The max operating pressure is 250 psi (air), or 750 psi (oil). Bore sizes are 40, 50 & 63mm (1.5, 2, 2.5") Rod lock & oversize rod options are available.

The HBB series linear slides are capable of handling heavy duty guided linear motion applications. The HBB, or ""base"" version, is designed to span the work area and tranlate the load between two support points. Two parallel precision ground case hardened, or stainless steel, support shafts are guided by four linear bushings and incorporated into the body assembly. The bearings are prelubricated to provide millions of trouble-free cycles. Composite bushings with standard or oversized shafting or linear ball bearings are available.

The HBB series features a machined, anodized one-piece aluminum body with tapped and counterbored through holes for mounting flexibility. Standard dowel pin holes provide precision mounting for the body and tool plate. The power behind the HBB series is Parker's premium NFPA aluminum, steel, or ISO cylinder. Standard piston wear bands allow the piston rod assembly to "float" in the bore thereby eliminating metal-to-metal contact. The result is dramatically greater cylinder seal life especially when the support shafts deflect under load. This ensures very long cylinder life with reduced maintenance and downtime. Available options include 3-position cylinders and slides without cylinders. Consult factory for other application needs.
