R 103861620 Bosch Rexroth - Linear Motion Component

Product Identification

R 103861620 Bosch Rexroth is a manufacturer reference associated with Bosch Rexroth linear motion technology. The number should be preserved exactly when identifying or ordering the component. Its specific product family, construction, dimensions and operating characteristics require confirmation against the manufacturer's catalogue before the item can be classified reliably as a linear bearing, ball bushing, runner block or another linear motion component.

The designation alone is not sufficient to establish its technical specifications. Bosch Rexroth manufactures several different linear guidance systems, and similar material numbers do not necessarily identify interchangeable products.

Confirmed Product Identification

The manufacturer reference R103861620 corresponds to LINEAR-SET LSAOE-A-16-DD, an open, adjustable linear ball bearing unit designed for a 16 mm shaft. This identification is supported by multiple specialist industrial distributors.

Technical Specifications - Bosch Rexroth R103861620

The listed outside diameter and length are bearing-related catalogue dimensions, not verified overall housing dimensions. Dimensions and operating characteristics are reported by specialist distributors and should be checked against the exact Bosch Rexroth drawing before final mechanical design.

What Does LSAOE-A-16-DD Mean?

The designation identifies the linear bearing unit's construction:

• LSAOE - Open, adjustable linear ball bearing unit series.

• A - Super linear ball bushing A configuration.

• 16 - Nominal shaft diameter of 16 mm.

• DD - Sealing arrangement on both sides.

The open design is intended for use with a compatible supported shaft arrangement, where the bearing unit must pass along the shaft support without interference.

The adjustable configuration allows operating clearance to be set according to the installation requirements.

Construction and Operating Principle

R103861620 uses recirculating balls to guide movement along a cylindrical precision shaft.

The bearing unit combines the linear ball bearing with its supporting housing. During operation, the balls circulate through the bearing while the unit moves along the shaft.

The open construction provides clearance for the shaft support. This distinguishes it from a closed linear bearing unit, which surrounds the shaft without a longitudinal opening.

The self-aligning design helps accommodate limited angular misalignment. However, correct shaft alignment and suitable mounting surfaces remain essential.

Selection and Interchangeability

Before replacing R103861620, verify the exact manufacturer material number, LSAOE-A-16-DD configuration, 16 mm shaft diameter, open housing geometry, mounting dimensions, adjustable clearance and sealing arrangement.

A closed linear bearing or a different Rexroth linear-set series is not automatically interchangeable, even when the nominal shaft diameter is identical.

Typical Applications

Open linear ball bearing units are commonly used in industrial automation, guided machine slides, linear positioning equipment, material handling mechanisms and supported-shaft linear axes.

These are typical applications of the product design, not confirmed OEM applications of the exact material number.

Installation and Maintenance

Mount the unit on a clean, compatible precision shaft and ensure that the open section is correctly oriented relative to the shaft support.

Check alignment, operating clearance and fastening before commissioning. Lubrication should follow Bosch Rexroth's instructions for the exact linear-set configuration.

Protect the ball tracks and seals from dirt during handling and storage.

Frequently Asked Questions

1. What is Bosch Rexroth R103861620?

It is an open, adjustable linear ball bearing unit designated LSAOE-A-16-DD.

2. What shaft diameter does it fit?

The nominal shaft diameter is 16 mm.

3. Is it an ordinary rotating ball bearing?

No. It is a linear motion bearing unit designed to travel along a cylindrical shaft.

4. What does DD indicate?

It identifies sealing on both sides of the linear bearing unit.

5. Is the bearing open or closed?

It is an open version, intended for a compatible supported-shaft arrangement.

6. Can operating clearance be adjusted?

Yes. The product is listed as an adjustable linear bearing unit.

7. Can it compensate for shaft misalignment?

The listed self-alignment capability is up to 30 arcminutes, subject to the manufacturer's operating conditions.

8. Can another 16 mm linear bearing replace it?

Not automatically. Housing geometry, open construction, mounting dimensions, adjustment and sealing must also match.
