It features a thick-walled outer ring with a crowned profile to accommodate misalignment and reduce edge stresses, ensuring a longer operational life. The KR47PPA is equipped with PPA seals on both sides, which provide excellent protection against contaminants and retain lubricant effectively. This ready-to-mount unit is based on a needle roller bearing and includes a solid stud with a fixing thread, allowing for simple and secure installation.
