Rexroth R161924282 Linear Guide Component

Bosch Rexroth R161924282 Linear Guide Component (HK 2505 KR – Manual Clamping Element)

 

The Rexroth R161924282 is not a moving guide rail itself, but a manual clamping / locking element used on linear guide rail systems (ball/roller rail systems).

Product Information

• Brand: Bosch Rexroth (Germany)
• Part number: R161924282
• Type: Manual clamping element (brake / lock unit)
• Series: HK 2505 KR
• Function: Mechanical locking of linear guide carriage
• System: Profile rail linear motion system (HIWIN/THK-compatible class)

What it actually is

This part is used to lock a linear guide carriage in position, meaning:

• Stops movement on linear rail
• Holds position under load
• Manual lever clamping (no electricity needed)
• Used for positioning, maintenance, or safety locking

System Role (Simple)

Linear guide rail + carriage
→ R161924282 clamping unit (this part)
→ locks carriage in fixed position
→ prevents movement under force

So it acts like a “mechanical brake for linear motion systems.”

Key Features

• Manual operation (no power required)
• High holding force (~1200–2000 N class depending condition)
• Compatible with SNS ball/roller guide rails
• Adjustable lever position
• Compact industrial design
• Long service life (hundreds of thousands of cycles)

Typical Applications

• CNC machine tool positioning
• Industrial automation slides
• Assembly stations
• Linear positioning systems
• Safety locking during maintenance
• Precision mechanical fixtures

Advantages

• Simple mechanical design (very reliable)
• No electrical or pneumatic supply needed
• Strong holding force for positioning
• Easy integration into Rexroth linear systems
• Long operational lifespan

Important Notes

• Not a PLC module ❌
• Not a sensor ❌
• Not a motor ❌
• Not a guide rail ❌
• It is a manual clamping / locking accessory for linear motion systems ✔

Precautions

• Must match correct rail size (size 25 system)
• Must be mounted properly to avoid misalignment
• Do not exceed rated holding force
• Requires periodic inspection for wear
• Only works with compatible linear guide profiles
