3088 universal joint with 30 mm bearing cups, 55 mm inside-circlip lock-up and 88 mm overall span. The BJ212 drawing specifies four 33×1.5 mm internal retaining rings, a greaseable cross and XHP322 axle grease. This is an inside-circlip design: verify the cup diameter, distance between the inner retaining faces and full cup-to-cup span before ordering.
3088 Universal Joint 30×55(88) mm | BJ212 Inside Circlip
Description
3088 universal joint is a greaseable cross-bearing assembly identified by three important dimensions: 30 mm bearing cup diameter, 55 mm inside-circlip lock-up and 88 mm overall cup-to-cup span. The referenced engineering drawing names the BJ212 series and confirms that this product uses internal retaining rings rather than external circlips.
The photographed 3088 universal joint includes one cross with four installed bearing cups, four C-shaped internal circlips and one grease fitting. The rings seat inside the yoke bores after the cups are pressed into position. An outside-circlip joint can look similar while using a different measuring method.
Product Features
Designed for propeller-shaft repair, the 3088 universal joint combines a machined cross with four precision bearing cups. The serviceable lubrication point supports scheduled greasing, while the snap rings establish the installed width.
- 30 mm nominal bearing cup outside diameter.
- 55 mm distance between the inside retaining faces, tolerance 0 / -0.2 mm.
- 88 mm total span across opposite bearing cup outer ends.
- Four 33×1.5 mm internal circlips shown in the drawing and product image.
- Greaseable construction for service and replacement applications.
Technical Specifications
The drawing for the 3088 universal joint specifies 20Cr for the cross and bearing cups, GCr15 needle rollers in size 2.5×13.8 mm, oil-resistant rubber seals and an M6x1 grease fitting. The assembly quantity is 108 needle rollers, four bearing cups, four seals, four circlips and one cross. The listed assembly weight is approximately 0.6 kg.

Cross-Reference and Application
For sourcing, the 3088 universal joint may be searched as 30×88 universal joint, 30×55(88) universal joint, BJ212 universal joint or inside-circlip cross bearing. These references identify the dimensional family but do not replace a physical comparison.
The 3088 universal joint is promoted for BJ212-related driveline service where the shaft yoke uses four internal retaining rings. Vehicle names, production years and shaft configurations can vary by market, so application claims should be confirmed with dimensions, a drawing, an original sample or a propeller-shaft assembly number.
How to Verify Fitment
Before ordering a 3088 universal joint, measure one bearing cup with a caliper, then measure the 55 mm lock-up between the inner circlip seating faces. Also check the full 88 mm span across opposite cup ends. Confirm the circlip groove arrangement, grease-fitting clearance, seal profile and cup shoulder shape against the original part.
During installation, clean the yoke bores and press each bearing cup evenly. Seat all four internal rings completely, then verify free movement with no axial clearance or binding. Use the lubricant specified by the service instructions.
Ordering Information
When requesting a quotation for the 3088 universal joint, send the quantity, BJ212 or shaft reference, dimensions and photos of the removed part. MR Driveline can review drawings or samples before confirmation.
Frequently Asked Questions
Is the 3088 universal joint measured as 30×88 mm?
Yes, 30×88 mm describes the cup diameter and total span, but the 55 mm inside-circlip lock-up is equally important. Include all three dimensions when comparing this internal-retention design.
Are the four retaining rings included?
The product image and drawing show four internal circlips. Confirm final kit contents on the quotation or purchase order.
