BS EN 1337-8:2007 Structural bearings. Guide bearings and restraint bearings

BS EN 1337-8 deals with the requirements for the design and manufacture of guide bearings and restraint bearings.

Guide bearings are bearings that provide restraint in one horizontal direction only, accommodates rotations and does not transmit vertical loads.

Restraint bearings are bearings that prevent movements in the horizontal plane, accommodate rotations and do not transmit vertical loads.

Guide bearings and restraint bearings are designed to:

• Transmit horizontal forces
• Allow vertical movements
• Allow movements in one or no horizontal directions
• Allow rotations
• Generate low resistance to movement
• Have durability appropriate to their intended use.

Guide bearings and restraint bearings are not intended to transmit vertical loads but they may be combined in one unit with the bearings covered in BS EN 1337-1:2000.

BS EN 1337-8 is of use to:

• Designers of bearings
• Manufacturers of bearings
• Construction workers using bearings
• Conformity assessors dealing with the technical aspects of bearings
• Quality control officers
• Testers.
