50.8 mm (2.0 in)

Product catalog summary
Specifications:
The document outlines specifications for modular belts and sprockets, including a nominal pitch of 50.8 mm (2.00 in) and surface types such as flat and rough top. The backflex radius is 85.0 mm (3.30 in) or 100 mm (3.94 in), with a consistent pin diameter of ø8.0 mm (0.31 in).
Materials and Colors:
Recommended belt materials are POM-NLaS K and POM-NL, with pins made from Pa6.6 N. Non-standard materials and colors are available as per the uni Material and Color Overview.
Procedures and Recommendations:
Thread inserts are recommended for fixture attachment, with an insert size of M5. The influence of attachments on the backflex radius should be considered.
Accessories:
Accessories include rubber tops and molded sprockets, with standard rubber color being black. Sprockets come in various sizes and configurations, including single and double rows.
Performance Parameters:
Details on permissible tensile force and belt weight are provided for different widths and materials. For instance, a 151 mm (5.9 in) belt has a tensile force of 7852 N (1765 lbf) for POM-NLAS/PA6.6 material.
Standards and Tolerances:
General belt tolerance is +0/-0.4% at 23°C/73°F and 50% RH. Maximum load per drive sprocket and spacing between wear strips are specified.
General Specifications:
Belt tolerance is +0/-0.4% at 23°C/73°F and 50% RH. Non-standard belt widths are available. Maximum load per drive sprocket varies by material, and maximum spacing between wear strips is specified.
Belt Dimensions and Load Capacities:
Belt widths range from 153 mm (6.0 in.) to 3965 mm (156.1 in.). Tensile force and weight vary by material and width.
Material and Color Options:
Belt materials include POM NLAS, POX-FR, and PP, with various color options. Pin and lock materials include PA6.6, PP, and PE.
Accessories and Additional Features:
Inserts can increase the contact area of the belt. POX-FREC has a surface resistivity of 1x103 Ohm. Various accessories like side guards are available.
Sprocket Information:
Sprockets are available in various sizes and configurations. Bore sizes and dimensions are customizable.
Additional Notes:
Specifications may change due to continuous development. For detailed information, contact Customer Service or visit the company's website.
