Description

The Ozak Linear Bush L25 OH is a standard single-type Ozak Linear Bush engineered for high-precision, low-friction linear motion along 25 mm hardened steel shafts. Featuring integrated lubrication oil holes, a 40 mm outer diameter, and a 59 mm overall length, it solves frictional wear and maintenance downtime by delivering dynamic load capacities up to 1,560 N and static load capacities up to 2,740 N.

The Ozak Linear Bush L25 OH delivers exceptional rotational accuracy and smooth linear travel for industrial automation and mechanical guide systems. Manufactured in Japan by OZAK, this standard single-length recirculating ball bushing features an integrated lubrication hole (L-OH type) along its outer steel sleeve, allowing seamless lubricant replenishment without disassembling the housing or linear guide assembly.

Designed to fit a 25 mm shaft diameter, the L25 OH utilizes precision-ground steel balls running smoothly in heat-treated raceways. Dual synthetic dust seals on both ends block airborne particulate ingress while retaining grease, ensuring long service life, ultra-low friction coefficients, and minimal maintenance intervention in demanding production environments.

Key Features & Benefits

• Integrated Lubrication Port (L-OH Series): Built-in oil hole on the outer sleeve permits direct grease or oil injection for non-stop continuous linear guide operation.

• High Rigidity Outer Sleeve: Precision-machined alloy steel outer cylinder provides dimensional stability and structural integrity under heavy radial stress.

• Dual Dust Sealing System: Factory-fitted double lip seals prevent dust, metal shavings, and debris from penetrating internal recirculating ball tracks.

• Optimized Recirculating Ball Circuit: Precision steel balls deliver smooth rolling motion with low rolling friction, minimizing shaft torque and positional lag.

• Exact Dimensional Interchangeability: Standardized ISO metric dimensions ensure straightforward drop-in replacement across global machinery frameworks.

Common Industrial Applications

• CNC Router & Milling Axis Drives: Provides precise multi-axis positioning on 25mm guide rods.

• Pick-and-Place Gantry Systems: Delivers rapid, repeatable linear motion in high-speed electronic assembly lines.

• Packaging & Labeling Machinery: Enables smooth reciprocating stroke motion under continuous operating duty.

• Automotive Assembly Automation: Mounts inside robot transfer arms and hydraulic press loading fixtures.

• Medical Diagnostic Equipment: Offers smooth, silent sliding motion with minimal vibration levels.

• Textile & Printing Presses: Maintains smooth travel along feed shafts subjected to paper lint and textile fibers.

• Automated Conveyor Transfers: Supports transverse slide plates in heavy material handling lines.

What is the primary advantage of the Ozak L25 OH linear bush compared to standard linear bearings?

The Ozak L25 OH linear bush features an integrated oil hole along its outer sleeve.

This design allows maintenance engineers to inject lubricant directly into internal ball tracks without disassembling housings, extending bearing lifespan and preventing thermal stress during continuous linear operation.

What shaft size and tolerances are recommended for installing the L25 OH Ozak linear bush?

The L25 OH is designed for a 25 mm nominal shaft diameter. For optimal clearance, minimal backlash, and smooth travel, pair it with an induction-hardened linear shaft (hardness 58–64 HRC) machined to a g6 tolerance grade.

Does the Ozak L25 OH linear bush come pre-sealed against industrial dirt and debris?

Yes, the Ozak L25 OH includes synthetic rubber double lip seals fitted on both ends. These dust seals retain internal grease while stopping particulate matter, metal chips, and ambient dust from penetrating recirculating ball tracks.
