LM-OP Split Graphite Copper Bushing Solid Inlaid Graphite Self-lubricating Linear Guide Bushing

Product Overview

LM-OP open type graphite bronze bushing (split linear bearing) is manufactured from high-strength high-lead brass alloy, with solid graphite plugs embedded evenly on the sliding surface. It is a self-lubricating sliding bearing that works without oil refilling during operation.

The open split structure allows easy installation on linear shafts, convenient gap adjustment. This bushing combines the high mechanical strength & wear resistance of bronze plus the self-lubricating property of graphite. It performs well under heavy load, low speed, high temperature, dust-prone environments where conventional ball bearings cannot work normally. Widely used for linear sliding motion in automation machinery, CNC equipment, packaging & textile machines.

Key Features

✅ Open Split Design: Easy assembly, adjustable clearance, fits round linear shafts perfectly

✅ Solid Graphite Self-Lubrication: No oil supply required, low friction coefficient, maintenance free

✅ High Load Capacity: High strength brass base, withstand heavy static & dynamic load

✅ Wide Temperature Range: Stable performance from -40℃ ~ +280℃

✅ Excellent Wear & Corrosion Resistance: Long service life in dusty, dirty working conditions

✅ Low Noise Operation: No rolling element noise, smooth linear movement

✅ Customization Available: Custom inner diameter, outer diameter, length & graphite layout upon drawings

Application Scenarios

CNC machinery, automatic assembly equipment, packaging machinery, textile machines, hydraulic equipment, woodworking machinery, injection molding machines, transport conveyor systems, linear guide sliding assemblies.

Technical Parameter Table

Notes

1. The matching shaft surface should be hardened and polished for longer service life.
2. This bushing is designed for low-speed heavy-load linear sliding, not suitable for high-speed rotation.
3. Pre-lubricate with grease on first installation to get optimal initial performance.
4. Custom drawings are welcome for special dimensions, non-standard graphite arrangement.
