WA-WS Series Universal Worm Gear Reducer<\/h2>\n

The WA-WS Series pairs the universal multi-angle WP housing with two of the most popular input orientations: WA<\/strong> (input from below, A-type) and WS<\/strong> (input from above, S-type). Both variants use a bare input shaft for belt, chain, or coupling drive, and both share a single housing casting that can be reoriented on site if the motor position changes in the future. Thirteen frame sizes from WP40 to WP250, ratios of 5:1 to 60:1, and output torques up to 3,025 N·m match the performance of the fixed-orientation DA and DS models while adding the flexibility of a universal industrial gearbox<\/strong> platform.<\/p>\n

Applications<\/h2>\n

Conveyor and Material-Handling Drives (WA)<\/h3>\n

Floor-level belt conveyors in warehouses, grain terminals, and recycling plants typically position the motor below the reducer. The WA orientation places the input shaft pointing downward, accepting a V-belt from a motor on the floor or a low-level bracket. This is the most common configuration for horizontal conveyor head-shaft drives, and the universal housing means the same unit can be rotated to S-type for future overhead-motor layouts without purchasing a new gearbox.<\/p>\n

Tank-Top Agitators and Mixers (WS)<\/h3>\n

Vertical-shaft agitators in chemical reactors, blending tanks, and CIP vessels position the motor above the reducer on a bridge or platform. The WS orientation places the input shaft pointing upward, accepting a belt or coupling from the motor above. The self-locking worm gearbox<\/strong> property at 25:1 and above holds the impeller stationary during batch transfers.<\/p>\n

Specifications<\/h2>\n

Values at 1,500 r\/min, continuous duty. WA and WS share identical torque, efficiency, and bearing ratings. All dimensions conform to the speed reducer gearbox<\/a> platform standards. contact us<\/a> for drawings.<\/p>\n

Construction<\/h2>\n

The WA-WS housing is the same one-piece grey cast-iron universal casting used for the W Series, with motor-mounting faces on six planes. The output is a solid dual-end shaft with foot pads on two perpendicular planes. All internal components are interchangeable with the DA, DS, KA, W, and every other single-stage WP model of the same frame size.<\/p>\n

Components and Spare Parts<\/h2>\n

Every wear component inside this reducer is available as an individual spare part from our Condell Park, NSW warehouse, enabling targeted replacement rather than full-unit swap. Full parts commonality with the entire WP single-stage family. One inventory covers WA, WS, DA, DS, KA, W, and more.<\/p>\n

Customer Reviews<\/h2>\n
\n
★★★★★<\/span><\/p>\n

We standardised on the WA for all our conveyor drives. Motor below, belt-driven. The universal casting means we can swap to S-type if a future layout change puts the motor above. Smart investment.<\/p>\n

★★★★☆<\/span><\/p>\n

The WS top-entry fits our reactor agitators perfectly. Same parts as the WA but motor mounts above. Spares commonality across both orientations saves us inventory cost.<\/p>\n

Lubrication<\/h2>\n

ISO VG 220–320 EP gear oil. WA (input below) uses the standard horizontal fill mark. WS (input above) may require a slightly higher fill to keep the upper bearing lubricated. First change at 100 hours, then 2,500 hours or annually.<\/p>\n

Frequently Asked Questions<\/h2>\n
\n1. What is the difference between WA and WS? +<\/span><\/summary>\n
Both use the same universal housing and gear pair. WA<\/strong> (A-type): motor input from below<\/strong>. WS<\/strong> (S-type): motor input from above<\/strong>. Switching between the two is simply a matter of rotating the input pulley or coupling to the appropriate face.<\/div>\n<\/details>\n
\n2. Does the WA-WS include a motor flange? +<\/span><\/summary>\n
No. Both use a bare input shaft for belt, chain, or coupling drive. For a direct motor flange, see the WDA-WDS Series<\/strong>.<\/div>\n<\/details>\n
\n3. Are WA and WS parts interchangeable? +<\/span><\/summary>\n
Yes, 100 %. They share the same housing casting, worm pair, bearings, and seals. Only the installed input angle differs.<\/div>\n<\/details>\n
\n4. How does the WA-WS differ from the DA-DS? +<\/span><\/summary>\n
The DA and DS use fixed-orientation housings<\/strong> with a motor flange. The WA and WS use a universal housing<\/strong> with a bare input shaft. The WA-WS can be reoriented on site; the DA-DS cannot.<\/div>\n<\/details>\n
\n5. What output shaft options are available? +<\/span><\/summary>\n
Standard: solid dual-end shaft<\/strong> with keyways. For hollow output, see the universal-series WPWKA (A-type) or WPWKS (S-type) models.<\/div>\n<\/details>\n
