Heavy-Duty Guide Rollers: selection, replacement and quotation support
Yoke and stud type guide rollers carry radial and side load in conveyors, cranes, stackers and steel equipment where contamination and shock are normal.
Cross references and catalog data support preliminary identification. Confirm the current drawing, load capacity, tolerances and application requirements before ordering. See the industrial bearing RFQ checklist for the full data set.
Guide roller types
Guide rollers are offered as yoke (caged or full-complement) or stud type (NUKR / KRV class), with thick-section outer rings for direct track running.
- Yoke rollers: NATR, NATV, NUTR
- Stud rollers: NUKR, KRV
- Full-complement for higher radial load
When to use a guide roller vs a combined bearing
A guide roller runs on a track and carries mostly radial load. A combined bearing adds an axial roller for side thrust guidance in a steel profile. Choose the combined bearing when side guidance and a compact profile-running unit are required; use guide rollers for simpler radial track duty.
- Radial track duty: guide roller
- Radial + axial guidance in a profile: combined bearing
- Heavy shock and contamination: sealed or full-complement
Heavy-duty execution
High-load positions use full-complement yoke rollers, larger stud diameters and sealed executions. State track hardness, speed, shock and relubrication needs so the right execution is selected.
- Full-complement yoke rollers (NUTR)
- Larger stud and hex for NUKR
- Sealed for washdown or dusty duty

Heavy-Duty Guide Rollers FAQ
How do I specify heavy-duty guide rollers?
Send the complete model, all suffixes, quantity, delivery country and a controlled drawing when available. Also state load, speed, environment and mounting details.
Can you verify an equivalent heavy-duty guide rollers?
Yes. Cross-reference numbers start the review, but interchangeability is confirmed from dimensions, internal design, adjustment, load capacity, lubrication and operating conditions.
What information is required for a quotation?
Provide the old marking, photos or drawing, critical dimensions, application, quantity and destination. Required inspection documents should be stated before quotation.
