What is the minimum order quantity (MOQ)?

Stock models can be supplied in small quantities, and non-standard bearings can be custom-made even in small batches. Send us the model number or drawing and we will confirm the MOQ with your quotation.

Can you supply bearings under our own brand?

Yes. NKEN offers full OEM service: your brand laser-marked on the bearing rings, custom colour boxes and labels, so the goods arrive ready for your shelf.

Do you provide free samples?

Yes, free samples are available for most catalogue models so you can test quality and fit before placing a bulk order.

What information do you need to quote?

The bearing model number (or the brand cross-reference number you currently buy), quantity, delivery destination, and any special requirements such as clearance, seals or branding. A drawing is enough for non-standard parts.

Which countries do you export to?

NKEN bearings are exported to more than 73 countries, with sea and air shipping options and export packing as standard.

Thrust ball bearing 511 series washers and ball cage for axial loads in rotary tables and presses

Thrust Bearings — 511 / 512 / 513 Ball & Roller Types

NKEN supplies thrust ball bearings in the 511, 512 and 513 series and thrust roller bearings (cylindrical and spherical) for equipment that carries pure axial load: rotary tables, crane and drilling hooks, presses, extruders and vertical pump shafts. Single-direction and double-direction executions are available, with flat or spherical housing washers and seating rings.

Thrust duty is also where our oilfield programme starts — rotary-table thrust bearings are a named NKEN speciality (see Oilfield & Drilling Bearings). The full 511/512 thrust ball range — 80 models — is tabled below; thrust roller types and large or special thrust bearings are produced to order.

511, 512, 513 thrust ball series, single and double direction
Thrust cylindrical and spherical roller bearings for heavy axial loads
Flat or spherical housing washers, with seating rings
Rotary table and hook executions for oilfield service
Large sizes produced to order, up to the group's 1000 mm bore range

Types	Thrust ball (511/512/513), thrust cylindrical roller, thrust spherical roller
Direction	Single and double direction
Washers	Flat or spherical housing washer
Applications	Rotary tables, hooks, presses, extruders, vertical shafts
Note	Thrust ball bearings are for axial load only — not radial load

Thrust Bearings — questions buyers ask

Which thrust bearing fits a drilling rotary table?

Rotary tables use heavy thrust ball or thrust roller bearings sized to the table model. Send the table make/model or the bearing dimensions (bore, OD, height) and we quote the NKEN execution — see also our Oilfield & Drilling Bearings page.

Can a 51108 carry radial load as well?

No — single-direction thrust ball bearings carry axial load only. If your position has combined load, tell us the loads and we will recommend a spherical roller thrust or angular contact solution.

Do you supply double-direction thrust bearings?

Yes, 522/523 double-direction executions with a central shaft washer are available in the same size steps as the 511/512 table.
