Product Overview
The SBS series is one of the most widely used hydraulic main pump platforms on Caterpillar mid-size excavators. Because these machines work under continuous high pressure and heavy load cycles, the rotary group — cylinder block, pistons, valve plate and swashplate — is the first area to show wear, typically as drifting, slow cycle times, abnormal noise or loss of digging force.
HYLINK manufactures the complete SBS rotary group and individual replacement components for SBS80, SBS120 and SBS140 pumps. Parts are produced from high-strength forged alloy steel and precision-cast bronze, machined on CNC lines to micron-level tolerance and inspected with CMM equipment, so a single worn component can be replaced without changing the whole pump — cutting repair cost and downtime for your customers.

l 100% performance test — every complete pump assembly is tested on our dynamic hydraulic test rig for pressure, flow rate and efficiency under full working load.
Packing, Shipping & Warranty
l Packaging — anti-rust protective film + heavy-duty foam cushioning + standard export fumigation-free wooden case (reinforced carton for small spare parts).
l Shipping — express courier (DHL / FedEx) for urgent repair orders; sea or air cargo for bulk orders.
