SL360 SL Type Oldham Coupling \u2013 160mm Bore 360mm OD Radial Misalignment Compensating Drive Shaft Coupling<\/h1>\n

The SL360 SL Type Oldham coupling<\/strong> is a three-component sliding-block coupling designed for connecting two coaxial drive shaft lines where significant radial displacement between shaft centrelines must be accommodated without transmitting radial load to the connected equipment bearings. With a nominal torque rating of 32500 N\u00b7m at 100 rpm maximum speed, 360 mm outer diameter, and a bore range of 160 mm, the SL360 serves drive connections in the full range of industrial machinery \u2014 from medium-duty pump and fan drives to large-scale industrial processing equipment. The radial displacement compensation of 6.4 mm, angular compensation of 0.5\u00b0, and axial accommodation of 5.7 mm make the SL Type one of the most flexible misalignment-compensating couplings available at this torque level.<\/p>\n

The SL Type coupling operates through a three-piece sliding-block mechanism: two identical cast iron flanged hubs, each mounted on one shaft, and a central polymer (or metal) slider block that engages with both hubs simultaneously through tongue-and-groove interfaces positioned at 90\u00b0 to each other. Torque is transmitted from the driving hub through the tongue-groove contact to the slider block, and from the slider block to the driven hub through the second pair of tongue-groove faces. Radial misalignment between the shaft centrelines is absorbed by sliding movement of the block within the hub grooves \u2014 the block translates in the plane perpendicular to the shaft axis as the coupling rotates, compensating for the offset continuously during operation. This mechanism produces a uniform angular velocity transmission \u2014 unlike some other misalignment-compensating coupling types that introduce cyclic velocity variation.<\/p>\n

The slider block is a replaceable wear element. At planned maintenance intervals, the block can be inspected for wear and replaced without removing either hub from its shaft, minimising maintenance downtime.

Coupling Assembly and Slider Block<\/h2>\n

\"SL360<\/p>\n

The SL360 slider block engages the two hub faces through precision-machined tongue-and-groove features. The tongue dimensions and groove clearances are controlled to minimise backlash while providing the sliding freedom needed for misalignment compensation. The standard slider block material is an engineering polymer selected for low friction, adequate compressive strength at the operating torque, and dimensional stability across the rated temperature range of -20\u00b0C to +70\u00b0C. For higher-load or elevated-temperature applications, a metal slider block is available.<\/p>\n

\n
\n

Large Radial Compensation<\/h3>\n

6.4 mm radial offset compensation eliminates the need for precision motor-to-driven equipment alignment on most plant installations, significantly reducing commissioning time and equipment cost.<\/p>\n<\/div>\n

\n

Constant Velocity Transmission<\/h3>\n

The Oldham mechanism maintains constant angular velocity ratio between input and output shafts at all rotational positions \u2014 unlike universal joint couplings which produce cyclic velocity variation proportional to operating angle.<\/p>\n<\/div>\n

\n

Replaceable Wear Element<\/h3>\n

The slider block is the only wear element in the coupling. It can be inspected and replaced without removing either hub from its shaft, minimising maintenance downtime and hub replacement cost.<\/p>\n<\/div>\n

\n

No Radial Force Transmission<\/h3>\n

The sliding mechanism absorbs shaft offset without transmitting significant radial forces to the connected shaft bearings \u2014 protecting motor bearings and driven equipment bearings from misalignment-induced overload.<\/p>\n<\/div>\n<\/div>\n
