Scope

This standard specifies the product classification, models, structural forms, technical requirements, test methods and inspection rules, packaging, marking, transportation and storage, and bearing selection for guide rail rotating ball bearings of highway bridges. This standard applies to guide rail rotating ball bearings with a vertical bearing capacity of 1.5 MN to 60 MN. 4. Classification, Models, and Structural Forms 4.1 Classification 4.1.1 Classified by displacement function: a) Dual-directional movable bearings: with vertical bearing, vertical rotation, and bidirectional sliding performance, designated as SX; b) Vertical movable bearings: with vertical bearing, vertical rotation, longitudinal sliding, and horizontal bearing performance, designated as ZX; c) Horizontal movable bearings: with vertical bearing, vertical rotation, lateral sliding, and horizontal bearing performance, designated as HX; d) Fixed bearings: with vertical bearing, vertical rotation, and bidirectional horizontal bearing performance, designated as GD. 4.1.2 Classified by horizontal bearing capacity: a) Type I bearings – with a design horizontal bearing capacity of 10% of the vertical bearing capacity, designated as JQZ(I)-201 6-spherical stainless steel plate; 11-upper anchor bolts; 2-upper bearing steel plate; 7-spherical modified polytetrafluoroethylene plate; 12-lower anchor bolts; 3-stainless steel plate; 8-lower bearing steel plate; 13-lower sleeve; 4-planar modified polytetrafluoroethylene plate; 9-upper anchor rods; 14-lower anchor rods. 5-ball cap; 10-upper sleeve; Figure 1: Dual-directional movable bearing structure; Figure 4: Fixed bearing structural schematic 5. Main Technical Features Compared with the traffic industry standard JT/T 873-2013, this standard achieves an overall improvement in bearing performance through innovations in bearing structure, materials, and content, with the following technical features: ?
