The SGCAT988 Tilt Cylinder is a massive, high-performance hydraulic actuator engineered for Caterpillar 988G and 988H Wheel Loaders. Designed to replace OEM Part Number 231-1955, this cylinder is critical for controlling the bucket’s “rack back” and “dump” functions in heavy-duty quarrying and mining operations.
As part of the loader’s Z-bar linkage, the Tilt Cylinder endures tremendous tension and compression forces during the breakout phase. SEIGO Machinery manufactures this component with oversized rod eyes and reinforced cylinder walls to prevent fatigue failure under maximum payloads.

Key Features & Performance
-
High-Speed Cycle Performance: Optimized for the rapid loading cycles of the CAT 988 series. Our sealing system is designed to handle high piston speeds without overheating, ensuring continuous truck loading productivity.
-
Reinforced Z-Bar Linkage Fit: Precision-machined mounting points ensure perfect alignment with the loader’s Z-bar linkage, eliminating play and reducing stress on pins and bushings.
-
Impact-Resistant Rod: The large-diameter piston rod is induction hardened to resist damage from falling rocks over the spill guard, a common hazard in wheel loader applications.
-
Mining-Grade Durability: Built to withstand the shock loads of penetrating blasted rock piles, ensuring long service life in the toughest quarry environments.
Applications
-
Quarry face loading (Shot Rock)
-
High-production truck loading
-
Stockpile management
