BOSCH Linear Guide Block SLH

BOSCH Linear Guide Block SLH

Features:

• High rigidity in all load directions – permits applications with just one runner block per rail
• High torque capacity
• Limitless interchangeability as all Ball Rail Systems can be combined at will with all Ball Runner Block versions within each accuracy class.
• Long-term lubrication is possible over several years
• End-face fastening thread for all attachments
• Quiet, smooth running thanks to optimally designed ball and ball chain return and guidance
• Different preload classes
• Excellent dynamic characteristics
• Can be used on all SNS/SNO Ball Guide Rails
• Ball Runner Block pre-lubricated at the factory.
• Ball chain for low noise level and best travel behaviour

Highlights of the ball runner blocks BSHP:

▶ Further increased travel accuracy up to a factor of six
▶ Significantly reduced frictional oscillations and low friction force level, particularly under external load
▶ Maximum precision
▶ Selected qualities
▶ Minimum quantity preservation in the accuracy classes XP; SP; UP.
(Impairment of the environment is reduced by the preserving agent)
▶ Patented entry zone increases the sequence accuracy
▶ All other advantages of Rexroth precision ball runner blocks integrated.

Ball entry:

▶ The balls are guided up to the start of the entry zone via the roller deflection.
▶ If the distance between the ball runner block (1) and the ball guide rail (3) is smaller than the ball diameter, the ball (2)
is put under load (preload) in pulses.
▶ The preload is increased in the entry zone and reaches its maximum in the load bearing zone. By doing so, the ball
transmits its force from the ball runner block to the ball guide rail.
▶ Due to the kinematic and geometric relations, a distance between the individual balls is set.
