7N7970 Bearing for Caterpillar Equipment

7N7970 is a straight-sleeve bearing used in Caterpillar articulated dump trucks. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The bearing is intended for installation in the specified Caterpillar articulated dump truck applications listed below. The available product data identifies the component by its Caterpillar reference number 7N-7970 and provides its basic construction, dimensions, and design features.

Fitment

• Caterpillar D250E articulated dump truck
• Caterpillar D250E II articulated dump truck
• Caterpillar D25C articulated dump truck
• Caterpillar D25D articulated dump truck
• Caterpillar D300B articulated dump truck
• Caterpillar D300D articulated dump truck
• Caterpillar D300E articulated dump truck
• Caterpillar D300E II articulated dump truck
• Caterpillar D30C articulated dump truck
• Caterpillar D30D articulated dump truck

Fitment should be checked against the machine model and the bearing dimensions before installation, especially where different bearing sizes or engine configurations may be available for the same equipment series.

Cross-reference numbers

The numbers 7N7970 and 7N-7970 identify the same bearing reference, with the second format using a hyphen in the part number. No additional supplier reference numbers are specified in the available product data.

Specifications

The component has a plain sleeve configuration without an inner groove, outer groove, or cross holes. The supplied dimensions describe the bearing itself: 2.17 in inside diameter, 2.36 in outside diameter, and 0.75 in overall length.

The available data does not specify an undersize or oversize designation, installation position, included components, or additional engine application details. These parameters should therefore be confirmed from the machine parts information and the removed bearing before assembly.
