PER.G211RPPB10 agricultural bearing 49.225×100mm
A spreader axle rolls into the workshop with a familiar complaint: the drive-side bearing has chewed through its seal after a season in fertilizer dust. The maintenance team reaches for a replacement with a 49.225 mm bore—not a common metric size—and the parts list points to PER.G211RPPB10. Before the purchase order goes out, there are a few checks that matter more than the unit price.
At a glance
- Specification: Value
- Model: PER.G211RPPB10
- Bearing type: Special deep groove ball bearing, single row, agricultural machinery
- Bore (d): 49.225 mm (cylindrical)
Start With the Mounting Envelope, Not Just the Bore
Agricultural machinery often uses inch-based or special bore sizes because the shaft and housing were designed around a complete assembly, not a catalogue bearing. This bearing is a single-row, special deep groove ball bearing with a cylindrical bore of 49.225 mm, an outside diameter of 100 mm, and a width of 33.338 mm. The 1.02 kg weight is useful for freight estimates, but it is not a substitute for checking the drawing.
A 50 mm bore bearing may look close on a caliper, but it will not restore the original fit. Confirm the shaft diameter, housing bore, shoulder dimensions, and axial location before you approve any substitute. Also check that the housing can accommodate the 100 mm outside diameter and the 33.338 mm width without preloading the outer ring against a dirty shoulder.

Use the table as a quick reference during enquiry, then attach the controlled drawing to the purchase order. If the application involves a flanged housing, eccentric locking collar, or a specific grease path, state it separately; those features are not defined by the base dimensions alone. You can compare related sizes in our Agricultural bearings category before narrowing the shortlist.
Verify Fit, Tolerances, and the RPPB10 Detail
Fit is where most procurement errors begin. The PER.G211RPPB10 may share a model number with previous purchases, but the bore and outside diameter tolerance bands still need confirmation against the shaft and housing drawings. A bearing that is dimensionally correct but too loose in the housing will creep; one that is too tight can distort the outer ring and shorten service life.
Ask for the inspection report, not just a catalogue page. The report should show actual measured values and the tolerance class used. For agricultural duty, also confirm radial internal clearance and the seal or shield arrangement shown in the drawing. The RPPB10 suffix is a procurement checkpoint in itself—do not assume it means the same protection as another supplier’s suffix.
- Bore and outside diameter tolerance bands against your shaft and housing drawings.
- Radial internal clearance for the expected speed, load, and operating temperature.
- Seal or shield type, grease fill, and relubrication path if the bearing is pre-lubricated.
- Cage material and riveting or spot-welding quality—this unit uses a stamped steel cage.
- Marking, traceability, and batch identification on the bearing and packaging.
Load Ratings and Service Duty: Read the Numbers in Context
The published basic dynamic radial load rating is 42996 N, and the basic static radial load rating is 28523 N. These are reference figures for bearing selection, not a guarantee that every agricultural load path is covered. Impact loads from uneven ground, PTO engagement, or a blocked conveyor can exceed steady-state calculations, so the static safety factor deserves attention.
Check the actual radial and axial loads, the speed, and the lubrication condition. A single-row deep groove ball bearing can carry combined loads within its design limits, but misalignment and contamination change the outcome. If the bearing sits at the end of a long shaft or in a housing that deflects under load, confirm whether the assembly provides enough stiffness. This bearing is rated for the duty described by its load figures; it is not a drop-in upgrade for a larger bearing simply because the bore matches.
What to Confirm About Interchange and Part Number
Buyers often search by the original European design reference and then order by appearance. That is risky. The safe route is to match the model number, dimensions, suffix, cage, and drawing. PER.G211RPPB10 belongs to the PER.G200 series (G20..RPPB10), and the number should appear consistently on the quotation, packing list, and bearing marking.
If a supplier offers an “equivalent” without a drawing, ask for the tolerance, clearance, cage, and seal details in writing. Use our bearing number reference to check how suffixes and series codes are structured, then compare that information with the controlled specification. A lower-priced substitute that changes the seal or clearance can cost more in downtime than it saves at the counter.
Lead Time, Packaging, and Supplier Checks
Agricultural maintenance windows are short. Ask whether the item is stocked, made to order, or assembled in batches, and get the lead time in writing. For seasonal repairs, a confirmed ship date matters more than a broad “available soon” reply. Clarify the minimum order quantity, the number of pieces per box, and whether mixed batches can be supplied.
Packaging should protect the bearing from dust and moisture. Confirm that the unit is individually wrapped, marked with the model and batch, and packed with enough protection for palletized freight. If the bearing is destined for a dealer or OEM line, ask for the certificate of conformity, inspection records, and traceability information before the goods leave the factory.
A Practical Ordering Sequence
Start with the shaft and housing measurements, then confirm the 49.225 mm bore, 100 mm outside diameter, and 33.338 mm width. Next, review the load ratings, clearance, cage, and seal detail against the application. Finally, lock down the part number, drawing revision, quantity, and lead time in the purchase order.
That sequence prevents the most common failure in agricultural bearing procurement: buying a dimensionally similar part and discovering the fit or protection detail is wrong during the repair.
