Bearing Heavy Responsibilities, Moving Steadily Forward: An Analysis of the Excellent Performance of PR711 PR712 PR721 Track Rollers

In the vast field of construction machinery, track rollers are an indispensable core component of the undercarriage system. They are not merely simple supports; they are crucial for bearing the equipment's weight and guiding the tracks to operate smoothly. Quanzhou Future Times Trading Co., Ltd. is committed to providing high-quality track rollers, including the PR711, PR712, and PR721 series, ensuring your heavy equipment maintains excellent performance and reliability under various demanding working conditions.

支重轮的分类：单边与双边（SF/DF）

支重轮通常分为单边（SF - Single Flange）和双边（DF - Double Flange）两种类型，以适应不同工况和设备需求：

• 单边支重轮（SF）：主要用于引导履带，提供侧向支撑，防止履带脱轨。它们通常设计为轻型或中型设备使用，在挖掘机中较为常见，提供灵活的转向能力。

• 双边支重轮（DF）：具有两侧法兰，提供更强的侧向支撑和更佳的稳定性。它们常用于推土机等重型设备，尤其是在复杂或高负荷作业环境中，以确保履带的精确对齐和承受更大的冲击。

Classification of Track Rollers: Single Flange (SF) and Double Flange (DF)

Track rollers are generally divided into two types: Single Flange (SF) and Double Flange (DF), to meet different working conditions and equipment needs:

• Single Flange (SF) Track Rollers: Primarily used to guide the track and provide lateral support, preventing derailment. They are typically designed for light to medium-duty equipment and are more common in excavators, offering flexible steering capabilities.

• Double Flange (DF) Track Rollers: Feature flanges on both sides, providing stronger lateral support and better stability. They are often used in heavy-duty equipment like bulldozers, especially in complex or high-load operating environments, to ensure precise track alignment and withstand greater impacts.
