Cylindrical Roller Bearing — ISO / DIN (Series 112) conform to ISO / DIN. As bearings & bushings, they are specified by the dimensions in the table below; this page also covers materials, finishes and typical uses.
What Are Cylindrical Roller Bearing — ISO / DIN (Series 112)?
Cylindrical Roller Bearing — ISO / DIN (Series 112) are bearings & bushings defined by ISO / DIN. They are selected by bore diameter and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
CAD Source Reference
This page is generated from an original native CAD part model (SolidWorks .SLDPRT) of the cylindrical roller bearing — iso / din (series 112) family maintained by our engineering team, covering 4 recorded size configurations. The technical drawing shown above is rebuilt parametrically from the dimensional table, so it always reflects the exact size and configuration you select. Native CAD files (STEP / SLDPRT) can be supplied with your quotation on request.
Materials & Finishes
Rolling-element bearings are supplied in through-hardened bearing steel (100Cr6 / SAE 52100) as standard, with stainless (AISI 440C) and ceramic hybrid variants for corrosive or high-speed service. The specification that matters is the tolerance class, the internal clearance and the cage and seal type — not a fastener property class.
Specification Guides
Each size, material and standard of Cylindrical Roller Bearing — ISO / DIN (Series 112) has its own reference page with the figures for that one configuration.
Goes With

Pricing
Cylindrical Roller Bearing — ISO / DIN (Series 112) are supplied to order. Pricing starts from approximately US$1.50 per piece for standard bore sizes in bearing steel, open or sealed; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Custom manufacturing · Made to drawing
Need a cylindrical roller bearing outside the standard range?
Dimensions, material, finish and form are specified from the drawing — a bearing & bushing outside the standard range is a variation on existing tooling rather than a new design.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
