Product Overview

The ORAE table in the uploaded catalogue contains two documented models. Rather than extending the range by assumption, GBC quotes these exact rows and asks for the machine or housing dimensions when an alternative is needed.

The published drawing and dimensional table follow the GBC insert-bearing catalogue for this ORAE series. It is defined by series-specific insert configuration; verify exact nppb suffix with rfq, a cylindrical insert profile shown in drawing, 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

Start with the exact model marking. ORAE30NPPB and ORAE40NPPB differ in bore, outside diameter and width. If the old suffix is incomplete, send a clear photo and measurements instead of guessing the sealing or material specification.

Installation Notes

Confirm the retention method and suffix meaning for the target machine before installation. Apply force only to the fitted ring during assembly and keep the sealing area free of burrs and contamination.

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 special replacement and cartridge-bearing positions where the ORAE dimensional envelope is specified. 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. The NPPB suffix is retained exactly as printed for ORAE; confirm seal and material interpretation with the RFQ because the supplied catalogue page does not define that suffix in detail.
