A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.Bearing Accessories are standard machine components serving for fixing rolling bearings on the shaft or in the housing bore.
They are Adapter Sleeves, withdrawal sleeves, locknuts and withdrawal nuts, locking washers and snap rings for bearings with snap ring groove on the outer ring.

Driving trolley line configuration introduction
Driving trolley line configuration introduction:
Unipolar safety wire contact accessories configuration list:
Relevant fittings for use in unipolar trolley wires; collectors, shoe pieces (contact shoes, carbon brushes, blades), access sections, power input parts, joint jackets, aluminium fittings, end shields, single hole holders / Four-hole clamp, four-hole lifting pylon, single-hole lifting pylon, current collector bracket, temperature compensator (expansion section), among them, collector, maintenance section, and temperature compensator (expansion section) that require extra charge .
(1) How many meters are required for the trolley line?
Sliding line length = workshop length x three-wire/four-wire (If using a three-phase three-wire slide wire, multiply it by three. If using a three-phase four-wire slide wire, multiply by four).
(2) Number of trolley wires = Number of trolley wires ÷ 4.5/6 (Lightweight trolley wire is 4.5m, and heavy trolley wire is 6 meters long)
(3) Number of collectors = number of trips x three-wire / four-wire (If using a three-phase three-wire sled, multiply it by three, if using a three-phase four-wire sled, multiply by four).
(4) Current collector bracket = number of vehicles = number of current collectors
(5) Aluminium connector = trolley wire length ÷ 4.5/6
(6) Number of connector sheaths = number of aluminum connectors
(7) Light steel contact angle steel bracket = four-hole lifting rack = workshop length ÷ 1.2/1.5 (The angle of light bracket is generally 1.2m or 1.5m, and the heavy one is 3m. )
(8) Power Input = Line x Power Supply x Span
(9) Four hole clamps; one span 2 pieces
(10) Heavy-duty trolley wire angle bracket = workshop length ÷ 2.4/3 (2.4m or 3m angle bracket for heavy-duty trolley wire)
(11) single hole lifting bracket = angle bracket x-ray system (wire system is the three-phase three-phase three-wire, three-phase four-wire four-line)
(12) single hole clamp = wire x2x span
(13) End sheath = wire x2x span
