Precision Split Steel Bushing with Lubrication Grooves

Qimao Metal Manufacturer is a professional Precision Split Steel Bushing with Lubrication Grooves supplier and factory. The steel body handles heavy loads and impact while the grooves hold grease or oil to reduce friction over long operating cycles. We see these used in press machines, conveyor rollers, and heavy equipment where downtime hits hard. The split design also means you can inspect wear without pulling everything apart. Each piece is finished with a slight interference fit tolerance so it stays put during rotation but still allows smooth movement. If you're tired of struggling with solid bushings in tight spots, this split version solves that problem.

Product Parameter (Specification)

Product Feature

1. Split body design – The Precision Split Steel Bushing lets you slide it onto a shaft from the side, so no need to remove other components.

2. Lubrication grooves – The grooves run parallel and spiral in some versions to spread grease evenly across the entire contact surface.

3. Material & coating – Made of medium-carbon steel with black oxide or light oil coating to prevent rust during storage.

4. Heat reduction – The groove pattern cuts down heat buildup even under continuous motion.

5. Consistent wall thickness – Both halves are machined at the same time, ensuring no mismatched halves.

6. Deburred edges – Edges are deburred so installation will not scratch your shaft.

7. Grease fitting compatible – Works with standard grease fittings if you want to add a port.

8. Stock availability – Multiple sizes available from stock.

9. Hardness tested – Each batch gets a hardness test to confirm 45–55 HRC.

10. Easy installation – No special tools needed; just common hand tools.

Application

1. Printing press rollers – On large printing press rollers where bearings sit between frames. With a solid bushing, you would have to pull the roller out completely. With this split version, you open it around the shaft and bolt it in.

2. Conveyor drive pulleys – In tight spaces under chutes, the split design of the Precision Split Steel Bushing with Lubrication Grooves allows installation without disassembly.

3. Construction equipment pivot points – Used on backhoe arms where pins wear unevenly.

4. Repair shops – Ideal for quick fixes on older machines with seized pins.

5. Steel mill roller tables – In high heat and dusty environments where regular lubrication is difficult. The grooves hold grease longer, reducing greasing frequency.

6. Marine equipment – Used on rudder shafts because you can replace bushings with the rudder still hanging in place.

7. Hard-to-access shafts – Any shaft that is difficult to access or surrounded by other parts where a solid sleeve would require complete machine disassembly.

Installation Guide

Installing this split bushing takes about ten minutes.

1. First, wipe the shaft clean, especially any rust bumps.

2. Next, spread a thin layer of grease inside both bushing halves. Don't fill the grooves yet. Position the bottom half under the shaft, then place the top half over it. The split edges should align with no gap. Now push the two halves together by hand until they sit flush with each other. If they feel tight, tap gently with a rubber mallet. For bolted versions, tighten fasteners in a crisscross pattern to avoid pinching.

3. After assembly, pump grease into the grooves through the fitting until you see the Precision Split Steel Bushing with Lubrication Grooves ooze out the ends. Turn the shaft by hand a few times to spread the grease. Check again after one hour of run time and add more grease if needed. No heat needed, no pressing tools. Just patience and clean hands.
