INA KBO 25 PP - Linear Ball Bearing for Industrial Guides

INA KBO 25 PP - A dependable linear bearing for industrial systems

Technical Description and Benefits

The INA KBO 25 PP is a linear ball bearing designed for shafts with a 25 mm diameter. Engineered for industrial-grade applications, it provides low-friction, precise linear motion with compact dimensions and effective sealing against contaminants. Its design supports high durability and stable performance under continuous operation in demanding environments.

Key benefits include:

• Long service life and contamination protection - dual-sided PP lip seals prevent ingress of dust, chips, and other debris, ensuring reliable performance over time.

• Smooth, precise linear motion - a configuration with five ball tracks ensures even load distribution, minimizing friction and backlash even under repetitive motion cycles.

• Compact and versatile design - with dimensions 25 × 40 × 58 mm, the bearing easily integrates into standard guide systems and shafts common in automation and mechanical assemblies.

• Robust construction for industrial conditions - durable steel components and sealed housing support sustained operation in automation, conveyor, and machinery environments.

These traits make INA KBO 25 PP a solid choice for applications where repeated linear movement, reliability, and low maintenance are essential.
