1912677 Bearing for Caterpillar

1912677 is a needle bearing used in Caterpillar equipment. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts). The supplied product data identifies the part as a bearing for Caterpillar excavators and a Caterpillar mobile hydraulic power unit.

The product is listed under the category “Needle Bearings.” The available data specifies the product number 1912677 and identifies the equipment manufacturer as Caterpillar. No additional bearing design details, such as the number of needle rollers, cage material, internal clearance, sealing arrangement, or load rating, are provided.

Fitment

The bearing is listed for the following Caterpillar equipment models and equipment series:

• Caterpillar 322C excavator
• Caterpillar 322C FM excavator
• Caterpillar 324D excavator
• Caterpillar 324D L excavator

• Caterpillar Mobile Hydraulic Power Unit

The model designations are reproduced according to the available equipment application data. The listing does not specify a particular machine production year, serial-number range, subassembly, or exact installation position for the bearing. Fitment should therefore be checked against the machine model and the part number recorded for the assembly being repaired.
