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.

Spherical plain rod end bearing with threaded shank for hydraulic cylinders and linkage systems

Spherical Plain Bearings & Rod Ends — GE / GEG / POS / PHS

NKEN supplies radial spherical plain bearings in the GE and GEG series and rod-end bearings (POS male-thread, PHS female-thread) for hydraulic cylinders, steering and suspension linkages, construction machinery and industrial automation — anywhere an oscillating joint must carry heavy load while accommodating misalignment. Steel/steel sliding pairs (greased, with seals on request) and maintenance-free PTFE-lined executions cover both heavy-duty and no-maintenance positions.

Representative GE sizes are tabled below. Rod ends follow the same bore steps with M-thread shanks; left-hand threads and stainless executions are available. If you are replacing an existing joint, the bore and OD in the table identify the size — send the designation or dimensions for a quotation.

GE and GEG radial spherical plain bearings, steel/steel or PTFE-lined

Spherical Plain Bearings — questions buyers ask

GE..ES or GE..ET — which do I need?

ES is steel/steel and needs grease — best for heavy, slow oscillation. ET is PTFE-lined and maintenance-free for positions that cannot be relubricated. Tell us the joint's load and access, and we confirm.

Do you supply rod ends with left-hand thread?

Yes, POS/PHS rod ends are available in right- and left-hand metric threads — mark LH in the designation when you inquire.

Can spherical plain bearings handle continuous rotation?

No — they are designed for oscillating and tilting movement under load. For continuous rotation, use a rolling bearing; tell us the application and we will suggest the right type.
