1. Plastic
Plastic guide rollers have several benefits over their metal counterparts. For one, they are much lighter, which makes them easier to handle and install. This can be especially important in applications where the rollers need to be moved frequently or installed in tight spaces. Plastic guide rollers are also resistant to corrosion, so they can be used in damp or wet environments without the risk of rust or other forms of corrosion. Additionally, they are often less expensive than metal rollers, which makes them a cost-effective option for many applications.

3. Hardened Steel
Hardened steel guide rollers have several benefits over other types of rollers. For one, they are extremely durable and resistant to wear and tear, which makes them long-lasting and reliable. The hardening process used to create these rollers also makes them more resistant to bending, twisting, and other forms of deformation, which can be important in applications where the rollers are subject to heavy loads or impacts. Hardened steel rollers are also able to withstand high temperatures and harsh environments, making them suitable for use in a wide range of applications. Additionally, they are often more rugged and heavy-duty than other types of rollers, which can be important in applications that require extra strength or support.
