Medium Duty Chain Driven Roller for Drums, Wheels, and Totes
Not every chain driven application requires the 2.5 in. roller platform used for loaded pallets. When the loads are drums, wheels, tires, totes, or medium-weight containers, the smaller 1.9 in. roller delivers the same positive chain drive in a more compact, cost-effective frame. The LEWCO CDLR19 is the straight-section workhorse for these applications — providing reliable chain driven transport without the heavier construction and higher cost of the 2.5 in. CDLR25 series.

Load Capacity
At 60 FPM with 4 in. roller centers on a 20 ft. length, the CDLR19 supports loads from 1,150 lbs. (1/2 HP, 48 in. width) to 7,500 lbs. (2 HP, any width). At 30 FPM, capacity reaches 7,500 lbs. across all widths at 1 HP and above. Maximum unit load is 400 lbs. per linear foot.
When to Choose the CDLR19 vs. the CDLR25
The CDLR19 (1.9 in. rollers, #40 chain, 400 lbs./ft. max) is the right choice when loads are medium weight and do not require the heavier 2.5 in. roller platform. Drums, wheels, tires, totes, and containers that stay under 400 lbs. per foot are well suited for the CDLR19. When loads include full pallets, heavy containers, or anything exceeding 400 lbs. per foot, the CDLR25 (2.5 in. rollers, #60 chain, 1,000 lbs./ft. max) is the correct specification.
Choosing the CDLR19 when it fits the application saves cost on rollers, chain, frame material, and motor sizing compared to over-specifying with the CDLR25.
System Integration
The CDLR19 integrates with the LEWCO CDRC19 curve for powered 90°, 45°, and 30° direction changes. Both share the same 1.9 in. roller diameter, #40 chain sprockets, and frame construction for seamless product transfer between straight runs and curves. Chain transfers and turntables are also available for routing and directional control within CDLR19-based conveyor systems.
Applications
The CDLR19 is commonly specified for drum and barrel handling lines, tire and wheel transport in automotive and tire manufacturing, tote and container handling in manufacturing and assembly, medium duty distribution and fulfillment, and any application requiring positive chain drive for loads that do not need the 2.5 in. pallet-rated platform.
