Custom Cold Forged Gearbox Splined Bushing High Torque Drive Couplings Manufacturer

Product Content:

The Custom Cold Forged Gearbox Splined Bushing High Torque Drive Couplings Manufacturer cold formed under our 1600-ton press for cold forming. What that does is compress the grain structure right along the spline root and flank – places where most fractures actually start. You get a denser tooth face without the micro-cracks you sometimes see with cut gears. The straight profile keeps installation simple: no flange to worry about, just push it into the housing bore and secure the retaining ring. We’ve seen these hold up well in applications like forage harvester gearboxes and steel mill roller tables – places where the drive train takes a beating daily. Custom tooth counts and pressure angles are possible, though we usually recommend sticking with standard involute forms unless you have a specific reason not to.

Product Specification:

Technical Details:

Custom Cold Forged Gearbox Splined Bushing High Torque Drive Couplings Manufacturer internal spline: involute form, 30° pressure angle per SAE J498 or DIN 5480. Overall length: 2.5″ to 5″ depending on housing depth. Wall thickness engineered for torque loads up to 8,000 ft-lbs. Material: 4140 or 8620 alloy, through-hardened to 45-50 HRC – core and surface match. OD ground to within 0.001″ TIR for concentricity with the internal bore. Bore broached and verified with go/no-go spline gauges per piece. Custom tooth modifications, non-standard lengths, and alternative materials available – require drawing or physical sample for exact match. Standard finish: oil dip. Optional: black oxide or zinc plating for high-humidity or chemical exposure environments.

Core Advantages:

• Custom Cold Forged Gearbox Splined Bushing High Torque Drive Couplings Manufacturer by cold forged – better fatigue life than cut or broached sleeves from annealed stock. Simple metallurgy.

• Ground OD as standard – eliminates the need for you to do any post-fit machining.

• Fitment options – we can match DIN, SAE, or JIS spline specs. Just send your mating shaft dimensions.

• No minimum quantity for standard sizes – we keep common ones on the rack.

• Each batch traceable – we stamp heat codes so you know what material went into that particular run.

Wide Usage:

• Agricultural equipment – Custom Cold Forged Gearbox Splined Bushing High Torque Drive Couplings Manufacturer direct mount on combine harvester gearbox outputs and round baler PTO drives. Handles the intermittent shock loads from varying crop densities and field conditions without tooth deformation.

• Construction machinery – Fits concrete mixer drum drives and excavator swing gearboxes. Stands up to reversing loads and continuous low-speed, high-torque rotation typical on job sites.

• Industrial power transmission – Used in steel mill roller tables and mining conveyor reducers where dust, grit, and continuous heavy loads are part of daily operation. Maintains concentricity under thermal expansion.

• Mobile hydraulics – Couples pumps to diesel engines on wheel loaders and crane swing motors. Compact design suits tight engine bay layouts with limited clearance.
