Product Overview

HC is selected from the catalogue by its spherical outer-ring geometry and its model-specific dimensional row. It is most useful for replacement jobs where the existing HC identification can be read and the housing is being retained.

The published drawing and dimensional table follow the GBC insert-bearing catalogue for this HC series. It is defined by series-specific shaft locking - confirm the exact hc suffix, a spherical outer ring, and the dimensional rows listed below. For broader bearing navigation, explore the Bearings range.

Dimensional Drawing

The drawing below is cropped directly from the supplied catalogue. Use its dimension letters with the table; do not scale the image to estimate dimensions.

Technical Parameters

Base metric rows and documented catalogue models are shown here. Inch-bore suffixes remain available where they appear in the catalogue; quote the complete suffix when an inch shaft is involved. Load ratings are catalogue values and should be checked together with duty, speed, lubrication and mounting conditions.

Selection and Housing Match

Record the complete HC marking, including any inch suffix. Match D, B and C to the catalogue drawing. Where the old marking is unreadable, send shaft and housing measurements with photos for cross-checking.

Installation Notes

Clean the spherical seat and check it for fretting or deformation before fitting a new insert. The self-aligning outer profile can accommodate mounting error between the insert and housing, but it does not correct a bent shaft or a damaged housing seat.

Where the machine uses a press or cartridge fit, apply assembly force through the fitted ring and keep load away from the rolling elements. Confirm the retention method from the machine drawing.

Catalogue Construction Notes

The catalogue describes insert bearings as single-row deep-groove ball bearings and shows dual-seal and triple-lip sealing arrangements within the product family. It also documents hardened inner-ring areas and an anti-rotation device used when a spherical insert is fitted with clearance in its housing. Confirm the exact suffix when a particular seal is required.

Typical Applications

This series is considered for industrial bearing units used on conveyors, agricultural machines and construction equipment. Application fit still depends on shaft size, housing geometry, contamination, relubrication needs and the real radial/axial load pattern. For food-processing equipment, specify any material, lubricant or washdown requirement explicitly rather than assuming the standard insert meets a hygienic specification.

Ordering Information

Model codes should be ordered exactly as documented. The catalogue uses -G for relubricatable versions in applicable SB/SA families, C-prefix notation for cylindrical outside-diameter variants, 2RS where the double-rubber-seal designation is part of the model, and +H for UK adapter-sleeve combinations. Not every suffix applies to every series.
