R067021040 Bosch Rexroth KBA-10-DD Linear Bushing 10x19x29

Overview

The Bosch Rexroth R067021040 KBA-10-DD is a Super Linear Bushing A designed for precision linear motion on a 10 mm shaft.

The closed linear bushing has dimensions 10x19x29 mm and incorporates five rows of balls. The Super A design provides misalignment compensation, helping the bushing operate smoothly where minor shaft deflection or installation inaccuracies are present.

The DD version features two integrated seals, providing additional protection against contamination in industrial linear motion systems.

Industrial Applications

Bosch Rexroth R067021040 is suitable for:

• Industrial automation
• Linear motion systems
• Production machinery
• Assembly equipment
• Packaging machinery
• Positioning systems
• Material handling equipment
• Special-purpose machines
• Mechanical engineering equipment

Super Linear Bushing A

The Super A series is designed with misalignment compensation.

Steel bearing plates with precisely machined ball tracks provide accurate ball guidance and allow the bushing to compensate for minor alignment errors.

This design helps reduce additional loads caused by shaft deflection or installation inaccuracies.

KBA-10-DD Designation Explained

KBA - Super Linear Bushing A with misalignment compensation

10 - nominal shaft diameter of 10 mm

DD - version equipped with two seals

The complete R067021040 / KBA-10-DD designation should be used when selecting a replacement.

Misalignment Compensation

A key feature of the Super A design is its ability to compensate for minor shaft deflection and alignment errors.

The design allows misalignment compensation of up to approximately 30 angular minutes (30').

This helps:

• Reduce edge loading
• Compensate for installation inaccuracies
• Improve load distribution
• Support smooth linear motion
• Reduce additional stresses in the guiding system

DD Double Sealing

The DD version incorporates seals on both sides of the linear bushing.

The sealing system helps:

• Reduce contamination ingress
• Protect the ball tracks
• Protect the rolling elements
• Retain lubricant
• Improve reliability in industrial environments

Linear Speed

The nominal maximum linear speed is 3 m/s.

Higher speeds of up to approximately 5 m/s may be possible under specific operating conditions, although service life can be reduced due to increased wear of plastic components.

Operational Advantages

• Original Bosch Rexroth linear motion component.
• Designed for a 10 mm shaft.
• Compact 10x19x29 mm dimensions.
• Super A design with misalignment compensation.
• Five rows of recirculating balls.
• DD version with two integrated seals.

Replacement and Selection

When replacing a Bosch Rexroth R067021040, verify:

• 10 mm shaft diameter
• 19 mm outside diameter
• 29 mm overall length
• Closed bushing design
• Super A series
• DD double sealing
• Required load capacity
• Linear speed
• Operating temperature
• Installation orientation

Dimensions alone should not be the only criterion when selecting an interchangeable linear bushing.
