Product Description

What this part is

Timken Torrington TRD1625 thrust bearing washer. A thrust washer is the hardened flat race that a thrust needle roller and cage assembly runs against. Bore Diameter: 1.0000 in (25.4 mm). Outside Diameter: 1.5625 in (39.67 mm). Overall Width: 0.1230 in (3.12 mm). Design Units: Imperial. Number Of Rows: 1.

Decoding the designation

TR — the Torrington inch thrust race family, now carried by Timken and by Koyo under the same numbers.

D — the thickness grade within that family. The TRD washer is the heavy-section race of the inch TR range, at 0.1230 in.

1625 — the size code in sixteenths of an inch: 16 sixteenths gives the 1.0000 in bore and 25 sixteenths gives the 1.5625 in outside diameter.

What these specs mean in practice

Overall Width: 0.1230 in (3.12 mm). The heavy 0.1230 in section spreads thrust load into a soft housing face or a shaft shoulder and gives the rollers a hardened, ground surface to track on, which is what keeps a thrust needle assembly from brinelling the parent material. Bore Diameter: 1.0000 in. Outside Diameter: 1.5625 in. The 1625 size code is shared across the TR washer range and the NTA needle thrust assemblies, so the washer and the roller assembly are ordered at the same number.

Quantity and configuration

Unit Quantity: 11 Pcs. The listing supplies eleven washers of the same designation. The matching thrust needle roller and cage assembly is the NTA-1625.

Interchange guidance
