THK RA8008 Cross Roller Bearing Replacement Review
Start THK RA8008 replacement review with old marking evidence, bore, outside diameter, width, mounting details, application, quantity, and target timing before RFQ.
Replacement Review Overview
A replacement request should keep old bearing evidence, machine requirements, and TFL Bearings quotation review separate.
RA8008 marking evidence
Send clear photos of the marking, suffix, package, or old order line.
Measured dimensions
Check bore, OD, width, mounting holes, ring structure, and seating face.
Preload and application
Confirm preload, clearance, accuracy, load direction, lubrication, and machine role.
Quantity and timing
Commercial review follows candidate validation and request-specific evidence.
Compatibility Checklist
Do not select by dimensions alone; mounting and internal condition can change replacement risk.
Marking and suffix
Capture full code, suffix, old label, and both-side bearing photos.
Mounting pattern
Check hole pattern, seating face, shoulder, and adjacent machine interface.
Preload or clearance
State known internal condition, rotation feel, accuracy, or rigidity requirement.
Application context
Send machine type, load direction, speed, lubrication, environment, quantity, and timing.
Replacement Review Boundary
Boundary wording keeps candidate review separate from final interchange.
What to Send TFL Bearings
A useful replacement RFQ combines old bearing evidence with machine context.
Engineering Decision Layer
TFL Bearings checks old model evidence, dimensional match, suffix or preload, mounting interface, and application risk before quotation.
Full marking, suffix, photos, and old order record
Starts the candidate path but does not close replacement validation.
Bore, OD, width, seating face, mounting holes, and ring structure
Controls mechanical fit and can block quotation confidence.
Preload, clearance, accuracy, torque behavior, and rigidity requirement
Changes rotation feel, heat, stiffness, and service risk.
Load direction, speed, lubrication, environment, and duty cycle
Decides whether the candidate route is suitable before RFQ.
Application Fit Notes for RA8008 Replacement
Application fit must be checked before the candidate is treated as quote-ready.
RFQ Process Depth Layer
Replacement review moves from old bearing evidence to dimensional validation, application fit check, and RFQ decision.
Old bearing evidence
TFL Bearings reviews the original marking, suffix, old order line, and bearing photos.
Dimensional validation
Bore, OD, width, ring structure, mounting hole pattern, and seating face are checked.
Application fit check
Load direction, rigidity, preload or clearance, speed, lubrication, and operating environment are validated.
RFQ decision
Quantity, timing, destination, and document needs are reviewed after technical evidence is clear.
Practical RFQ Checklist
Prepare these details before asking TFL Bearings to review THK RA8008 replacement.

FAQ
Yes. TFL Bearings can review THK RA8008 as a candidate when old marking evidence, dimensions, mounting details, application, quantity, and timing are supplied.
No. Treat it as a starting reference. Dimensions, mounting, preload, accuracy, load direction, application, and quantity must be checked before RFQ.
Send model or marking, bore, outside diameter, width, mounting details, drawing or photos, application, load direction, accuracy or preload notes, quantity, and target timing.
Yes. A drawing, sample photo, or measured bearing can support review when it shows mounting interface, ring structure, dimensions, application, and quantity.
Availability, price, and quotation timing are reviewed only after model, dimensions, drawing or photo, application, quantity, and delivery context are clear.
