The JU060XP0 sealed four-point contact bearing measures 152.4 × 171.45 × 12.7 mm. LYDL catalogs this six-inch size as LYDL-060UU.
Send a section drawing showing the bearing seats and service route. Request confirmation of the LYDL configuration, performance and inspection scope before ordering.
The JU060XP0 sealed four-point contact bearing has a 152.4 × 171.45 × 12.7 mm envelope and is listed by LYDL as LYDL-060UU. This six-inch reference can be evaluated for a rotary module with services routed through its center.
The useful passage is defined by the assembled shaft, retainers, connectors and moving service bundle. It is not automatically equal to the bearing bore.
| Dimension | Inches | Millimeters |
|---|---|---|
| Bore, d | 6.000 | 152.400 |
| Outside diameter, D | 6.750 | 171.450 |
| Axial width, B | 0.500 | 12.700 |
| Radial section | 0.375 | 9.525 |
Reserve the bearing seat first, then draw the remaining passage. Include assembly-tool access and connector removal space. A design that passes a bare cable may still prevent its connector from being installed.
The LYDL sealed Type X series table identifies this size as LYDL-060UU. Nominal dimensions do not replace the approved tolerances and supply specification.
A cable loop must remain clear of rotating hardware at both travel limits, during acceleration and after the equipment is serviced. Show the fixed attachment, moving attachment and bend radius specified by the cable manufacturer.
For a hose bundle, include stiffness, pressure effects and the forces transferred through its supports. A bundle passing near the center can still apply a variable force if its restraints are poorly located. Record these forces separately from the payload.
| Interface | Review before releasing the design |
|---|---|
| Limited-angle cable loop | Clearance throughout travel, strain relief and replacement access |
| Slip ring | Its own mounting, reaction restraint and alignment requirements |
| Rotary fluid union | Pressure, leakage provisions and independent support instructions |
| Central tube or conduit | Wall thickness, shaft-seat support and interference with retention |
Continuous rotation usually requires a suitable rotary interface; a flexible cable loop alone should not be assumed to permit unlimited turns. Follow the interface supplier’s requirements rather than using the bearing as an unspecified support for every component.

| Rating | Converted SI value |
|---|---|
| Dynamic radial | 7.873 kN |
| Dynamic axial | 12.633 kN |
| Dynamic moment | 478.378 N·m |
| Static radial | 13.656 kN |
| Static axial | 34.073 kN |
| Static moment | 1103.862 N·m |
These rounded values are converted from the Kaydon JU060XP0 entry in reference [1], not confirmed LYDL performance. Dynamic ratings use a one-million-revolution L10 basis; static values assume rigid support. Full ratings cannot be applied simultaneously. The listed 410 rpm limit carries the catalog condition of loads up to 20% of dynamic capacity. Confirm the actual duty and LYDL supply ratings before approval.
For a module carrying a gripper or sensor, separate payload loads from the forces introduced by electrical and pneumatic connections. Check the most restricted service position as well as the mechanically highest-load position; they may occur at different angles.
Define an inspection point for passage clearance and another for output runout. These verify different requirements. This is a proposed design scenario, not evidence of a completed LYDL installation.
Do not let a cable, conduit or retainer contact the bearing seals. Specify the operating environment and select the LYDL grease and seal material accordingly. Double sealing helps retain lubricant but does not make the assembly a pressure barrier.
The housing and shaft must support the rings without relying on the service tube to correct alignment. Confirm the mounting fits and internal clearance or preload before the mechanical design is frozen.
| Brand | Reference | Naming notes |
|---|---|---|
| KAYDON | JU060XP0 | J: standard steel with two nitrile seals; X: four-point contact; P: separator code; final 0: precision code. |
| INA / Schaeffler | CSXU 060.2RS | CSX: four-point family; U: section series; .2RS: sealing on both sides. |
| NSK | NBX15212DD | Sealed NBX catalog configuration; retain the DD suffix when checking the complete designation. |
The cited entries share the nominal 152.4 × 171.45 × 12.7 mm envelope. Compare tolerances, internal condition, sealing and rating methods before interchange. A brand suffix is not a LYDL accuracy or performance guarantee.
If the service package can be reduced, JU050XP0 has a smaller 127 mm bearing bore. Its housing diameter changes as well, so the seats must be redesigned. JU070XP0 offers a 177.8 × 196.85 × 12.7 mm comparison envelope when more central space is needed.
Browse the sealed Type X category for published options.
For the bearing quotation, request the agreed ring and ball materials, cage, lubricant, seals, internal condition and applicable ratings. For the complete module, separately identify connector access, permitted service forces and routing drawings.
Agree dimensional inspection and marking requirements for LYDL-060UU. Keep packing clean until assembly; service-installation debris should not be allowed onto the seal surfaces.
Not on the basis of the bearing bore alone. The hollow shaft, shoulders and retention reduce the available opening. Check the connector envelope, insertion angle and assembly sequence in section.
A central route does not prevent cable twist. Select a suitable slip ring or other rotary interface for continuous motion, or define a limited-angle loop within the cable supplier’s bend and twist limits.
Yes, when it transfers force or moment to the rotating assembly. Describe attachment positions and measure or obtain the force range over travel; do not treat it as a constant without evidence.
That cannot be assumed. Compare the union’s alignment and support requirements with the assembled module, including deflection under load and the union’s reaction restraint.
Include a section drawing, service layout at travel limits, load cases, speed or motion cycle, environment, quantity and acceptance requirements. This lets the supply proposal address both the bearing envelope and installation constraints.
Quote JU060XP0 reference / LYDL-060UU and include the assembled passage dimensions—not just the required bearing bore. Request the proposed configuration and quotation.
