Frequently Asked Questions
Q: What are the dimensions and material of the BS TRB-3648 thrust washer?
A: The BS TRB-3648 is a precision thrust washer with an inner diameter of 2.250 inches, outer diameter of 3.000 inches, and thickness of 0.060 inches. It is manufactured from chrome steel SAE 52100, through-hardened for durability and load capacity in material handling equipment applications.
Q: What equipment types and brands does the BS TRB-3648 fit?
A: The BS TRB-3648 thrust washer is compatible with electric lift trucks and material handling equipment from multiple OEM manufacturers. Verify your equipment model and bearing stack dimensions match before ordering to confirm fitment.
Q: What are the cross-reference and equivalent part numbers for the BS TRB-3648?
A: The BS TRB-3648 is interchangeable with INA TWA-3648, Koyo TRB-3648, and TWB3648. An equivalent fractional variant is TRA-3648, but you must verify fitment with your specific equipment before substituting, as dimensional tolerances may differ.
Q: How long does a precision thrust washer typically last in service?
A: Thrust washer lifespan depends on load, operating conditions, and alignment. Chrome steel SAE 52100 through-hardened washers typically provide extended service life in properly aligned assemblies. Inspect regularly for wear or scoring, and replace if damage is visible or if bearing preload becomes excessive.
Q: Does the BS TRB-3648 require any special handling or storage?
A: Store in a dry environment to prevent corrosion of the chrome steel surface. Handle carefully to avoid dropping or impacts that could crack the washer. Inspect the surface for defects before installation, as micro-cracks or surface damage can lead to premature failure under load.
