Which industrial bearing types can you supply?

We support combined bearings, track roller bearings, full-complement cylindrical roller bearings, back-up rollers, cross roller bearings, special guide rollers and Standard NbV profiles.

Can you cross-reference Winkel, INA, SKF or other bearing numbers?

Send the complete designation, dimensions and application. We can review equivalent series and replacement references, but the proposed item must be confirmed against mounting and operating data.

What information is required for a bearing quotation?

Provide the model, d × D × B dimensions, quantity, application, radial and axial loads, speed, temperature, lubrication, sealing requirement and delivery country. A drawing or marking photo is helpful.

Do you manufacture non-standard bearings and rollers?

Drawing-based dimensions, profiles, shaft ends, seals, grease, clearances and mounting features can be reviewed. Minimum quantity, tooling and lead time depend on the design.

Which track roller series are commonly requested?

Common searches include NUTR, NNTR, PWTR, NUKR, KR, KRV, NATR, NATV, CF and LFR series, including yoke type rollers and stud type cam followers.

Which full-complement cylindrical roller bearing series are available?

Frequently requested series include SL01, SL02, SL04, SL05, SL06, SL18, SL19, RSL, NCF, NJG, NNCL and NNCF.

Custom Track Rollers | Drawing-Based Bearings

Name: Special Track Roller Bearings
SKU: special-track-roller-bearings

Product Overview

Special Track Roller Bearings

Drawing-based guide rollers, profiled outer rings and modified track bearings for non-standard machinery.

Selection Drawing and operating data required

Lead time Engineering review required

Input required Model, dimensions or controlled drawing

Non-Standard Track Rollers

Special track rollers can incorporate profiled outer rings, modified studs, unusual widths, special seals, high-temperature grease or application-specific mounting features.

Typical Modifications

V-groove, U-groove and crowned running surfaces
Custom stud threads and eccentric collars
Alternative seals and lubrication holes
Special bearing steel and heat-treatment requirements

Reference Groups

Special Track Roller Bearings series and model references

Use these groups to identify the requested design. A reference is not an interchange approval; dimensions, suffixes and operating conditions must still be checked.

Design group	Common references or options
Profiled outer rings	V-groove, U-groove, concave, crowned and drawing-based profiles
Modified mounting	Custom stud threads, smooth studs, bores and eccentric collars
Environmental variants	Alternative seals, lubrication holes and high-temperature grease
Material variants	Bearing steel and application-specific heat-treatment requirements

Information required for selection

Controlled drawing: Dimensioned drawing with tolerances, revisions and critical characteristics.
Mating track: Track geometry, hardness, surface finish and alignment.
Operating duty: Load direction, speed, shock, duty cycle and expected service life.
Environment: Temperature, contamination, corrosion exposure and lubricant restrictions.
Commercial data: Prototype and annual quantity, target delivery and destination.

Verification

Drawings, inspection records and application evidence

Evidence is matched to the quoted product and order scope. We do not present another supplier's factory media, certificates or customer projects as our own.

Technical drawings

Reference sheets support identification. Controlled manufacturing drawings require model and supplier confirmation.

Inspection records

Request dimensional, marking, packing or supplier-document checks with the RFQ. Availability is confirmed before order placement.

Factory and equipment media

Only dated media supplied by the selected manufacturing partner or captured during the relevant inspection is used as evidence.

Customer applications

Cases are published only with permission or in anonymized form using verified order and application facts.
