Welded Double-Acting Cylinders

HBU2508-ORB Welded Double-Acting Hydraulic Cylinder

HBU SeriesWelded · Double-acting20.7 MPa (3000 PSI)

The same 65.5 kN (14,726 lbf) thrust and 20.7 MPa (3000 PSI) rating as the HCL 2.50 × 8, but closing at 406.4 mm (16 in) instead of 514.4 mm (20 1/4 in) — the choice when the retracted envelope sets the limit. 38.1 mm (1 1/2 in) rod, 25.4 mm (1 in) pin, SAE #8 port with 1/2 in NPT available. Weight: 8.6 kg (19 lb).

How to order

HBU2508-ORB reads as: HBU series / 25 → 63.5 mm (2.50 in) bore / 08 → 203.2 mm (8 in) stroke / ORB port. (For the HBU 2.00 in bore group, see the catalog notes on the series page.)

Features

  • Same heavy-duty construction as the HCL: threaded gland, ductile-iron piston, honed tube
  • Short 406.4 mm (16 in) closed length for tight mounting envelopes
  • Rod induction-hardened to HRC 45–50, hard-chrome plated
  • SAE #8 port with 1/2 in NPT available at order

Frequently asked questions

Why does the HBU2508-ORB close shorter than the HCL2508-ORB?

The HBU packs the same 63.5 mm (2.50 in) bore and 203.2 mm (8 in) stroke into a 406.4 mm (16 in) closed length — 108 mm shorter than the HCL — using a more compact internal layout.

What bore range does the HBU series cover?

From 38.1 mm (1.50 in) to 127 mm (5.00 in) with strokes up to 1219.2 mm (48 in) — the widest coverage in HCIC's welded family.
