<\/p>\n

The SLR Series Self-Lubrication Roller Chain combines standard ANSI \/ ISO roller-chain geometry with a sintered-bushing self-lubrication system, eliminating the need for scheduled re-oiling throughout the chain’s service life. A vacuum-impregnated, oil-bearing sintered bushing releases a continuous micro-film of lubricant into the pin\u2013bushing interface under heat and pressure \u2014 the same zone where conventional chains wear fastest when lubrication is inadequate or missed.<\/p>\n

The sintered bushing extends slightly beyond the inner plate face, forming a physical labyrinth seal that restricts the entry of airborne dust, textile fibres, grain particles, and other abrasives into the bearing joint. Paired with a chemically plated, surface-tempered bearing pin, this sealed-joint architecture produces a chain that outperforms externally lubricated standard chains in dusty, dry, or lubrication-restricted environments. All SLR chains are dimensionally interchangeable with standard ANSI \/ ISO roller chains.<\/p>\n

How the Self-Lubrication System Works<\/h2>\n<\/div>\n

<\/p>\n

\n

<\/p>\n

\n
01<\/div>\n

Vacuum Impregnation<\/p>\n

Sintered bushing is saturated with high-viscosity oil under vacuum during manufacture \u2014 every pore filled, no air pockets.<\/p>\n<\/div>\n

<\/p>\n

\u203a<\/span><\/div>\n

<\/p>\n

\n
02<\/div>\n

Thermo-pressure Release<\/p>\n

Operating heat and mechanical pressure cause the bushing to release a micro-film of lubricant directly into the pin\u2013bushing interface.<\/p>\n<\/div>\n

<\/p>\n

\u203a<\/span><\/div>\n

<\/p>\n

\n
03<\/div>\n

Sealed-Joint Protection<\/p>\n

Extended bushing lip creates a labyrinth barrier, blocking dust and abrasives while the tempered pin resists surface wear.<\/p>\n<\/div>\n<\/div>\n

Because the lubricant is stored inside the joint rather than applied externally, SLR chains resist the abrasive contamination that causes premature wear in standard chains \u2014 particularly in textile, grain-handling, and food-conveying environments.<\/p>\n<\/div>\n

<\/p>\n

\n
\n
<\/div>\n

Key Advantages<\/h2>\n<\/div>\n
\n

<\/p>\n

\n

Maintenance-Free<\/p>\n

No scheduled re-lubrication after installation \u2014 eliminates labour cost and unplanned downtime from missed oiling intervals.<\/p>\n<\/div>\n

\n

Contamination Resistant<\/p>\n

Extended sintered bushing + sealed-joint geometry blocks dust, grain, textile fibres, and metal particles from the bearing zone.<\/p>\n<\/div>\n

\n

Lower Total Cost<\/p>\n

Longer wear life, zero lubricant consumption, and fewer emergency replacements reduce total operating cost over the service period.<\/p>\n<\/div>\n

\n

Drop-In Compatible<\/p>\n

Identical ANSI \/ ISO face dimensions \u2014 retrofit into existing drives without sprocket changes or re-engineering.<\/p>\n<\/div>\n

\n

Quieter Operation<\/p>\n

Continuous lubricant film at the pin\u2013bushing interface reduces metal-to-metal contact noise \u2014 critical on food-processing and packaging lines.<\/p>\n<\/div>\n

\n

Material Options<\/p>\n

Carbon steel (standard), stainless steel SS316, and nickel-plated variants cover a wide range of corrosion-resistance requirements.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n
<\/div>\n

Typical Applications<\/h2>\n<\/div>\n

SLR chains are the preferred choice wherever conventional \u9396<\/a> lubrication is restricted, contaminating, or maintenance-prohibitive:<\/p>\n

Sprocket Selection<\/h2>\n<\/div>\n

Because SLR chains are dimensionally identical to ANSI \/ ISO standard chains, no special sprockets are required. Select sprockets by the same criteria as a standard drive:<\/p>\n

    \n
  • Pitch match:<\/strong> Sprocket pitch must equal chain pitch exactly \u2014 e.g., 25.4 mm for SLR-80 (16A-1).<\/li>\n
  • Tooth count:<\/strong> 17\u201325 teeth on the drive sprocket for most industrial drives; higher tooth counts reduce polygonal effect at high speed.<\/li>\n
  • Multi-strand:<\/strong> For duplex or triplex SLR chains, use matched multi-strand sprockets to distribute load evenly across all strands.<\/li>\n
  • High-torque single shaft:<\/strong> Taper-bushed sprockets with double-strand SLR chains are an effective solution where space is limited and torque is high.<\/li>\n<\/ul>\n

    Matching sprockets for every SLR chain size are stocked as standard catalogue items. We can supply chain-and-sprocket matched sets \u2014 contact us with your chain number and drive layout.<\/p>\n<\/div>\n
