Cardan Shafts
SWP-A Telescopic Long Cardan Shaft with Split Bearing Housing
SWP-A Telescopic Long Cardan Shaft with Split Bearing Housing with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
SWP-A is a telescopic long cardan shaft with a split bearing housing. The SWP table is organized around swing diameter, rated torque, fatigue torque, operating angle and length compensation, while the split housing affects support and maintenance planning. Treat shaft span, bearing support and flange phasing as one selection problem. The published model tables contain 15 size rows and provide torque values spanning 16–1250 N·m, operating-angle values spanning 10 °. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.

Engineering Context
This model is best understood from its own construction: Long telescopic shaft with split bearing housing; Length compensation supports relative movement; Fatigue torque and bearing-support geometry require joint review Industry selection practice checks torque and speed together with the movement, shaft interface, installation envelope and maintenance conditions allowed by that construction.
Technical Notes
- Model symbols, units and empty or placeholder cells are shown as published.
- Dimension letters must be interpreted with the relevant assembly drawing.
- Published values support preliminary review and do not replace final engineering confirmation.
Assembly Drawing
Information Required for Selection
- State span, travel, bearing-housing position and operating angle
- Compare rated/fatigue torque, swing diameter, speed and flange geometry
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Why does the split housing matter?
It changes support, access and alignment planning around the rotating shaft.
Can telescopic travel be specified independently?
No. Travel, installed length, angle and torque must be checked as a combined driveline.
Are the published values final ordering values?
No. They are preliminary engineering data; confirm the selected model, drawing, dimensions, materials, standard and suitability with RONGXING DRIVE.
Technical data is provided for preliminary selection. Confirm the final model, dimensions, materials, applicable standard and operating suitability with RONGXING DRIVE before quotation, manufacture or installation.
