Overview
The 25TRC is provided with tapered rollers to maintain product orientation through curves on gravity-pitched conveyor lines. On a standard straight-roller curve, products tend to drift toward the outside rail because the outside path is longer than the inside path. The 25TRC’s tapered rollers solve this mechanically — each roller is wider at the outside of the curve and narrower at the inside, creating a differential rotation speed that naturally steers products toward the inside and keeps them centered through the turn.
This curve section is commonly used with LEWCO 1912, 1916, and 2514 gravity roller conveyors. It provides a versatile tapered curve option that integrates into existing LEWCO gravity conveyor systems using the same bolted butt coupler connection.

How Tapered Rollers Maintain Product Alignment
On a gravity-pitched conveyor line, products flowing through a standard straight-roller curve drift toward the outside edge because the outside path covers more distance than the inside path. Guardrails can contain this drift, but they create friction, noise, and potential product damage.
Tapered rollers eliminate drift at the source. Each roller is wider at the outside of the curve (2.500 inches) and narrower at the inside (1.687 inches). As the product rides across the roller, the larger outside edge rotates through a greater distance per revolution than the smaller inside edge. This speed differential steers products toward the inside of the curve, keeping them centered without touching the guardrails. The result is smoother flow, less product damage, and consistent alignment as items exit the curve and continue to the next section.
Compatible Straight Sections
The 25TRC is designed to pair with multiple LEWCO gravity roller conveyor models. Compatible straight sections include the LEWCO 1912 (1.9 in. x 12 ga., 260 lbs/roller), the LEWCO 1916 (1.9 in. x 16 ga., 250 lbs/roller), and the LEWCO 2514 (2.5 in. x 14 ga., 290 lbs/roller). The 25TRC connects to each of these using the standard bolted butt coupler system.
Applications
The 25TRC is commonly used on gravity decline conveyor lines where products must change direction while maintaining alignment, packaging lines where cartons and cases need to arrive at sealing or labeling stations in a consistent orientation, e-commerce fulfillment systems that use gravity pitch to move orders between pick zones, distribution center conveyor layouts with multiple directional changes on a single gravity run, and any LEWCO gravity conveyor system where standard straight-roller curves cause product drift or misalignment on pitched sections.
Options
- Galvanized roller tubes for corrosion-resistant applications
- Guardrails for additional product protection
Selection Assistance
Choose the 25TRC when your LEWCO gravity conveyor line is pitched for decline flow and products are drifting to the outside of curves on standard straight-roller sections. If your conveyor is level and products are pushed by hand rather than flowing by gravity, standard straight-roller curves (such as the 2514C or 1916C) are typically sufficient and more cost-effective.
