OT, NT, T Series | High Strength Steel Chain Rollers
OT, NT, T Series
Top Styles
These rollers come in a variety of capacities, frame and top styles. They can easily be modified for any application.
FRAME TYPES
The OT, NT, T Rollers are fabricated from high strength steel. Load plates of 37.5-ton and higher capacities undergo a special machine process to minimize side-to-side movement of chain. The rollers can also be used inverted, as static conveyors.

The ERF Roller has no top plate and is often used where a trunnion mount is required, where an existing “foot pad” will become the roller’s top plate, or where the load has a built-in cavity mount. Used upside down, the ERF Rollers become a heavy-duty conveyor allowing the load to slide with extremely low friction.

The Super Heavy Duty Rollers are the highest capacity rollers that Hilman offers as standard models. 150 & 200 Ton frames come in Long (L) or Wide (W). Wide frame versions are offered with one complete (wide) chain or with two individual chains with a center plate (C) dividing them.

The Wide Body Rollers are wider and shorter in overall length. They are typically used when the OT, NT or T roller might be too long or if a larger contact area is desired. WB Rollers utilize two separate chains that provide a wider footprint. Increasing the footprint means the load is spread over a greater area, thus minimizing ‘point’ loading.

Options & Modifications
There are several options & modifications that can be applied to this roller series. We can also create a complete custom design to suit your specific project.
MOUNTING
OT and NT are available with standard bolt-on or welded mounting hole patterns. The top plates add extra strength to the frame and variety to mounting capabilities, making one type ideal for cavity mount, bolt-on or weld mount.
ACCU-ROLL BLOCK
This roller series has the option available to add two end-blocks on either end of the roller frame. The end-blocks have a drilled and tapped hole pattern that allows for the addition of an external guidance system (Accu-Roll) later on. In many cases, guidance systems can be interchanged. These models can be particularly handy for users who frequently need to change the type of track that the rollers will ride upon.
TURNTABLES & ROCKER TOPS
Additional components for OT and NT rollers include Turntable and Transverse and Longitudal Rocker tops. Turntables & Rocker tops are particularly advantageous in applications where the rolling surface is imperfect. In applications where the rollers with Accu-Roll are required to follow a slightly irregular or skewed track, they provide the ability to navigate the track without binding. They are available in 5 to 75 tons or can be completely customized to fit your project. Learn more about our Custom Tops.
