Pneumatic clamping and braking units UBPS R1810 .40 51

Description

• Clamps and brakes with spring energy accumulator
• Positive locking integrated contact profiles ensure maximum axial and horizontal rigidity, and thus an excellent braking effect
• Dynamic and static stabilization in the axial direction
• Clamps and brakes without pressurization (spring energy)
• Compact design, compatible with DIN 645

Features

• Up to 1 million clamping cycles
• Up to 2,000 emergency braking operations
• Integrated all-around sealing
• High continuous output
• High positioning accuracy
• Mechanical gate valve gear mechanism
• Solid, rigid steel housing, chemically nickel-plated
• Extremely low air consumption
• Maintenance-free
• 5 million clamping cycles (B10d value) – the B10d value is not attained with the PLUS connection
• Can be used on all SNS roller guide rails
• Very high axial holding forces of up to 7700 N at 5.5 bar release pressure with high-power spring energy accumulator
• Increased holding force of up to 9,200 N thanks to additional pressurization on the air-plus port

Product description

Functional principle

Air pressure: 0 bar

Clamps and brakes with spring force

In the event of a pressure drop, the clamping or braking effect is generated via a dual acting gate valve gear mechanism, each with one spring assembly (spring energy accumulator).

An integrated quick-exhaust valve provides for short reaction times.

Air pressure: 4.5 - 8 bar (MBPS)

5.5 - 8 bar (UBPS)

Decompression with air pressure

The clamping profiles are held apart by the compressed air.

Free movement is possible

Fields of application

Clamping

• in the event of loss of pressure

• during assembly work and standstill of the machine without energy

• of machine tables from machining centers

• of z-axis positioning in the resting position

Braking

• in the event of energy failure

• in the event of a pressure drop

• support of the emergency stop function

• support as brake for linear motors

Mounting

Note for mounting

• Stop surfaces can be used on two sides.

• Make sure the connection structure is rigid.

• Use only purified air. The prescribed filter mesh size is 25 μm.

• Observe the mounting instructions prior to commissioning.

• Check whether the sealing lips of the end seals are resting evenly on the roller guide rail. Realign if necessary.
