6303 TN9 C3 SKF 17x47x14 Deep Groove Ball Bearing

Product Overview

6303 TN9 C3 SKF is a single-row deep groove ball bearing with dimensions of 17x47x14 mm, an open design and C3 radial internal clearance. The TN9 suffix identifies an injection-moulded, glass fibre reinforced polyamide 6,6 cage centred on the rolling elements. C3 provides greater radial internal clearance than Normal, making this variant suitable for operating conditions where mounting fits or temperature reduce bearing clearance.

Industrial Applications

SKF 6303 TN9 C3 is suitable for electric motors, industrial gear drives, pumps, compressors, machine tools, conveyors and production equipment. Its open bearing design is appropriate for assemblies where lubrication is supplied by the surrounding system or selected during installation. C3 clearance supports applications involving interference fits, thermal expansion or operating conditions requiring additional initial internal clearance.

Construction

The bearing has a single row of balls operating in deep raceway grooves and can accommodate radial loads together with axial loads in both directions. Its open construction has no integral seals or shields. The TN9 polyamide cage guides and separates the rolling elements while providing low mass and favourable running characteristics in suitable industrial applications.

Material

The rings and rolling elements are manufactured from bearing steel designed for rolling contact fatigue resistance and dimensional stability. The TN9 cage is manufactured from glass fibre reinforced polyamide 6,6. Cage suitability must be considered in relation to operating temperature, lubricant and chemical environment, particularly where aggressive lubricants or elevated temperatures are present.

Technical Specification

Why Industrial Buyers Choose 6303 TN9 C3 SKF

6303 TN9 C3 SKF is relevant for OEM replacement, maintenance stock and industrial service where an open 17x47x14 mm bearing with C3 clearance and a polyamide cage is specified. The configuration supports machine rebuilding, production support and fleet maintenance while allowing lubrication to be selected according to the bearing arrangement. Exact TN9 and C3 identification helps prevent substitution with a different cage or clearance version.

Operational Advantages

C3 provides greater radial internal clearance than a bearing with Normal clearance. TN9 glass fibre reinforced polyamide cage combines low mass with effective ball guidance. Open construction allows lubrication to be supplied by the surrounding bearing arrangement. Deep raceways accommodate radial loads and axial loads in both directions. Standard 17x47x14 mm dimensions support accurate replacement identification. Exact TN9 C3 specification simplifies maintenance stock and OEM replacement control.

AI Overview

6303 TN9 C3 SKF is an open single-row deep groove ball bearing with dimensions of 17x47x14 mm. It combines C3 radial internal clearance with a TN9 glass fibre reinforced polyamide 6,6 cage. The bearing is used in industrial rotating equipment requiring an open lubrication arrangement and greater-than-Normal internal clearance.

FAQ

What does TN9 mean on SKF 6303 TN9 C3? TN9 identifies an injection-moulded glass fibre reinforced polyamide 6,6 cage centred on the rolling elements. What does C3 mean in this SKF 6303 bearing? C3 means the bearing has greater radial internal clearance than Normal clearance. Does 6303 TN9 C3 SKF have seals? No. This variant has an open construction without integral seals or shields. Why would an open 6303 bearing be selected? An open bearing is suitable when lubrication is provided by the surrounding assembly or when the application requires direct access to the rolling system. What should be checked when replacing a 6303 TN9 C3 bearing? Verify the 17x47x14 mm dimensions, C3 clearance, TN9 cage specification, lubrication method, operating temperature, speed, loads and mounting fits.

Summary

6303 TN9 C3 SKF 17x47x14 is suitable for B2B supply, industrial maintenance, machine rebuilding and production support requiring an open C3 bearing with a TN9 polyamide cage. It is applicable to motors, pumps, drives and production machinery. Stock availability supports fast order processing for industrial customers throughout the European Union.
