Name: 243-5220 Open Deep Groove Ball Bearing GCr15 Steel For Caterpillar C6.6 C7.1 C9 C13 C15 C18 Diesel Engine Replacement Spare Parts
Brand: GLOBALMACHEX
SKU: 243-5220
Availability: InStock
Rating: 5 (1 reviews)

243-5220 open deep groove ball bearing is dedicated replacement spare part for Caterpillar C6.6, C7.1, C9, C13, C15 and C18 series diesel engines. It is precisely forged and machined from GCr15 high-carbon chromium bearing steel with optional P0/P6/P5 precision grades. The single-row open steel ball structure bears radial loads and slight bidirectional axial loads simultaneously. The open design without seals delivers excellent heat dissipation and outstanding high temperature resistance, adapting to harsh working conditions of construction machinery diesel engines with long-term high temperature, engine oil immersion and dust. It can directly replace OEM engine bearings on site, serving as core durable spare parts for maintenance and overhaul of all series heavy-duty Caterpillar diesel engines.

1. Product Overview

243-5220 deep groove ball bearing is specially matched for full series Caterpillar diesel engines from C6.6 to C18, with dimensions fully compliant with Caterpillar OEM drawing standards. It adopts open single-row steel ball structure without dust shields. It is mainly installed on crankshaft, fan and hydraulic pump transmission support positions of diesel engines fitted on Caterpillar excavators, wheel loaders, mining trucks and generator sets. When engines run continuously at high temperature with circulating engine oil flushing, the open structure quickly dissipates heat generated during operation to avoid high-temperature seizure. The simple and stable overall structure enables easy disassembly and assembly. During engine maintenance, this bearing can be replaced separately without disassembling the whole power assembly, greatly cutting equipment downtime and operation losses of mining and construction fleets.

2. Material & Processing Advantages

GCr15 High Carbon Chromium Bearing Steel Blank: Integrally forged from national standard GCr15 bearing steel, treated with complete quenching and tempering heat treatment. Uniform hardness and fine stable metallurgical structure of steel balls and raceways deliver excellent resistance to fatigue, pitting and high-temperature spalling, perfectly adapting to continuous high-temperature working conditions of engines.
Single-Row Deep Groove Load Structure: Standard arc deep groove raceway provides high fitting degree with steel balls, which can stably bear radial loads and buffer slight bidirectional axial impact forces, meeting the stable operation requirements of engine crankshaft and auxiliary transmission parts.
Open Heat Dissipation Design Without Seals: No rubber dust seal covers. Engine oil fully circulates inside the bearing, and heat generated by high-speed rotation can be quickly carried away by circulating oil, solving the problem of heat accumulation, grease failure and seizure of sealed bearings under high temperature.
Super-Finished Mirror Raceway Machining: Mirror-level super-finish grinding on inner and outer raceways achieves ultra-low surface roughness, reducing rolling friction and temperature rise of steel balls. No abnormal wear or noise failure occurs during long continuous operation.

3. Precision Grade Selection Guide

P0: Standard general precision with high cost performance, suitable for routine engine maintenance and daily equipment repair of medium and small construction machinery
P6: Tighter dimensional tolerance for raceway and outer diameter improves assembly concentricity, reduces running vibration and heat generation, ideal for heavy-duty mining fleets working 24 hours non-stop
P5: High-precision grade for complete engine overhaul and crankshaft/transmission performance upgrade, with greatly improved high-speed running stability and concentricity, applicable to core engines of high-power generator sets and heavy mining trucks

4. Quality & Installation Instruction

243-5220 engine ball bearing is strictly manufactured to Caterpillar OEM specifications. The standard open structure requires no secondary grinding, and can be directly installed on engine bases of all Caterpillar C6.6/C7.1/C9/C13/C15/C18 series. Every finished product passes full inspection on GCr15 material hardness, internal clearance, raceway finish, dimensional tolerance and high temperature resistance before delivery. Custom P0/P6/P5 precision grades are available for bulk orders.

Installation steps:

Thoroughly clean engine mounting base and shaft journal surface to remove carbon deposits, waste oil and metal impurities;
Press the bearing evenly onto the shaft journal, never strike the bearing outer ring or steel ball area directly;
Fill engine lubricating oil of OEM specification after assembly, to ensure oil fully circulates inside the bearing;
Assemble engine auxiliary parts, start equipment for no-load debugging, and put into operation after confirming no abnormal noise or excessive temperature rise.

5. Application Scenarios

Widely applied to engine repair & replacement of Caterpillar excavators, wheel loaders, mining dump trucks and stationary generator sets equipped with C6.6, C7.1, C9, C13, C15, C18 engines, export wholesale of Caterpillar construction machinery spare parts, and regular engine maintenance of large open-pit mines and highway infrastructure engineering fleets. It solves common failures of original bearings such as abnormal running noise, excessive high temperature, steel ball pitting wear, raceway spalling, loose transmission clearance, lubrication failure and seizure. The open bearing features outstanding heat dissipation, effectively extending service life of engine transmission parts and saving spare parts purchasing costs for complete equipment overhaul.
