HMK Linear Ball guide bushing is a recirculating ball linear sliding component composed of housing matrix, integrated ball retainer and GCr15 bearing steel balls. 

We provide two mainstream housing material options: bronze linear ball guide bushings for heavy load working condition and aluminum linear ball guide bushings  for lightweight equipment. Bronze and aluminum Cylindrical straight and integrated flanged two styles for different mounting demands.

The built-in ball retainer separates steel balls evenly to reduce friction, realize long-term oilless self-lubricating operation, no frequent oil filling required. All ball sleeves are precision machined with strict dimensional tolerance, It belongs to the affordable IKO and Mismi bushings.

Core Advantages

1. Diversified Housing Material Selection 

Bronze housing: High strength, wear resistant, withstand heavy radial load for high-frequency reciprocating motion.

Aluminum housing:Ultra-light weight, good heat dissipation, cost saving for light-duty automation equipment.

That's the difference between copper-based and aluminum-based ball bushings.

2. Low Friction & Smooth Reciprocating Sliding

Integrated precision ball retainer isolates GCr15 steel balls, stable rolling movement, low noise, small friction coefficient.

3. Oilless Self Lubricating Structure

No regular lubrication maintenance needed, avoid oil leakage, suitable for clean, dusty workshop environment.

4. Interchangeable With IKO & MISUMI Standard Sizes

Complete standard outer & inner diameter specifications, straight/flanged shape can directly replace imported brand ball sleeves.

5. Custom Machining Service Support

Custom inner/outer diameter, length, flange size, housing material and logo engraving per customer drawings.
